The values of x in the triangles and the missing lengths are solved below

Given that the triangles are special triangles with 45 degree angle, we have

Hypotenuse = Leg√2

So, we have

Here, we use the trigonometry ratios

figure 5

cos(60) = 7/y

y = 14

x = √(14² - 7²)

x = 7√3

figure 6

cos(30) =2√3/y

y = 4

x = √(4² - (2√3)²)

x = 2

figure 7

cos(60) = x/10√3

x = 5√3

y = √((10√3)² - (5√3)²)

y = 15

figure 8

sin(30) = x/18

x = 9

y = √(18² - 9²)

y = 9√3

Here, we have

Area = (d/√2)²

Area = (16/√2)²

Area = 128

Area = 13 * 6 * sin(60 degrees)

Area = 39√3

Here, we have

tan(K) = 48/14 = 24/7

tan(J) = 14/48 = 7/24

tan(D) = 6√2/3 = 3√2

tan(E) = 3/6√2 = √2/4

Here, we have

tan(23) = x/53

x = 22.50

tan(43) = 36/x

x = 38.61

tan(28) = x/y

tan(45) = x/82

So, we have

x = 82 and tan(28) = 82/y

x = 82 and y = 154.2

Here, we have

tan(65) = h/30

h = 64.34

Here, we have

RQ = 14tan(56)

QS = 14tan(32)

So, we have

RS = RQ - QS

RS = 14tan(56) - 14tan(32)

Evaluate

RS = 12

Hence, the length RS is 12 units

The Earth has distinct layers, with the inner core being the most solid, the outer core being liquid, and the mantle and crust being solid. These layers resulted from the Earth's molten state.

The Earth was molten when it first formed. As it began to cool, it began to separate into layers. The denser materials, such as iron and nickel, sank to the center to form the core. Lighter materials, such as silicon and oxygen, floated to the surface to form the crust. The Mantle, the thickest of the Earth's layers, sits above the core. It is composed of hot, dense rock, and is responsible for much of the Earth's volcanic and tectonic activity. The outer core, which surrounds the inner core, is made up of liquid metal and creates Earth's magnetic field. The crust, which is the outermost layer, is divided into plates that move and interact with each other, causing earthquakes, volcanic eruptions, and mountain formation. The reason for this layering is due to the differences in density among the materials that make up the Earth. The heavier elements sank to the center to form the core, while the lighter elements floated to the surface to form the crust.

a. the distribution of humans around the world

b. the principles for solving border disputes

c. life cycles of plants and animals

d. features such as mountains, volcanoes, rivers, and glaciers"

The correct answer is:

c. It reduces the amount of dissolved oxygen in aquatic environments.

Thermal pollution refers to the increase in water temperature in aquatic environments caused by human activities, particularly the discharge of heated water from industrial processes or power plants into rivers, lakes, or oceans. This increase in temperature can have various negative effects on aquatic ecosystems.

One of the significant impacts of thermal pollution is the reduction in the amount of dissolved oxygen in water. Warmer water has a lower capacity to hold dissolved oxygen compared to colder water. As the temperature rises, the amount of dissolved oxygen decreases, making it more challenging for aquatic organisms, such as fish and other aquatic species, to survive.

Chemical weathering

Explanation:

Weathering can be defined as breakdown or wearing away of rocks by agents of weathering which are: rain, wind e.t.c.

We have 3 types of weathering:

a) Physical weathering

b) Biological weathering

c) Chemical weathering.

Chemical weathering is one of the types of weathering that occurs in rocks. It is defined as the GRADUAL weathering or wearing away of rocks due to chemical reaction of rain water and the minerals that are present in rocks.

Chemical weathering is said to be a GRADUAL weathering process because as the rain water or air reacts with the minerals in the rock, some parts are worn away, these parts are carried away by agents of weathering ( rain or wind) and fresher areas are exposed for more weathering and the process continues.

Chemical weathering is a GRADUAL AND CONTINUOUS PROCESS that occurs over a certain period of time before the rock is completely worn or weathered away.

A cirque that has been flooded with ocean water and is now found below sea level is called tarn.

A cirque is a bowl-shaped depression with steep sides, formed by glacial erosion. When a glacier retreats, it leaves behind this feature, which may fill with water from precipitation or melting ice. If the cirque is located near the coast and the sea level rises, ocean water may inundate it, transforming it into a tarn.

Tarns can be found in various parts of the world, including coastal areas that have experienced glacial activity in the past. As glaciers erode the landscape, they sculpt the underlying bedrock, creating distinctive landforms such as cirques, moraines, and drumlins. When these glacial features become submerged due to rising sea levels or other geological processes, they can create unique underwater landscapes and habitats.

In conclusion, a cirque that has been flooded with ocean water and is now below sea level is called a tarn. These unique features result from the interaction of glacial erosion and rising sea levels and can provide valuable insight into the geological history and processes of the regions in which they are found.

Answer:

the answer is B irans interior plateau

Explanation:

this is the answer because the irans interior is sorrounded by mountains and two unihabitable  deserts called  Dashte kavir and the other one is called kavir e lut

Iran's Interior Plateau is the Middle Eastern plateau that is surrounded by mountains and contains two uninhabitable deserts. The correct option is B.

As magma from deep within the Earth pushes toward the surface but is unable to penetrate the crust, many plateaus are created. Instead, the massive, flat, impermeable rock above it is raised by the magma.

According to geologists, the Colorado Plateau may have received its final lift beginning around ten million years ago from a cushion of magma.

The Zagros Mountains in the west, the Caspian Sea in the north, the Persian Gulf in the south, and the Indo-Gangetic Plains in the east border the Iranian plateau. According to our interests, the Iranian plateau, which spans a huge physical area, includes the entirety of modern-day Iran.

Eutrophication in a lake happens when excessive nutrients cause algal blooms, oxygen depletion, and ecological imbalances. Addressing it involves reducing nutrient inputs, implementing wastewater treatment, and promoting sustainable agriculture.

When a lake is considered to be eutrophic, it means that the lake has excessive amounts of nutrients, particularly nitrogen and phosphorus.

These nutrients can come from various sources such as agricultural runoff, sewage discharge, or industrial waste. The high nutrient levels in the lake stimulate the growth of algae and other aquatic plants.

As a result, the lake experiences an overabundance of plant life, leading to a phenomenon known as an algal bloom. The bloom can cause several negative effects on the lake ecosystem.

Firstly, the dense growth of algae blocks sunlight from reaching deeper water layers, inhibiting the growth of submerged plants and affecting the distribution of species.

Additionally, as the algae die and decompose, bacteria consume oxygen, leading to oxygen depletion in the water, which can result in the death of fish and other aquatic organisms.

The eutrophication of a lake disrupts the natural balance of the ecosystem, impacting water quality, biodiversity, and overall ecological health.

It can also have economic implications, as the presence of algal blooms can render water unsafe for recreational activities and reduce the aesthetic value of the lake.

To mitigate eutrophication, measures such as reducing nutrient inputs, implementing wastewater treatment, and promoting sustainable agricultural practices are often employed.

A volcanic eruption forming a new island shows an interaction between the Geosphere and hydrosphere. So, the correct option is (d).

What is Geosphere?

Our planet Earth interacts with different spheres to sustain life. There are four spheres in which the Earth interacts, namely the atmosphere, hydrosphere, biosphere, and geosphere. The atmosphere deals with the air component of the earth which envelops the planet and shows different layers, the hydrosphere deals with the water component of the Earth whether in the form of liquid, solid or gas, biosphere deals with the interaction of all the biotic (living) and abiotic (non-living) components, and lastly geosphere deals with the solid part of the earth including core, mantle, and crust.

Volcanic eruption takes place in the geosphere resulting in the eruption of hot magma onto the earth's surface. When this magma starts to accumulate under the water i.e., hydrosphere, a system of layers starts to form resulting in the formation of a seamount which is beneath the water. When this seamount starts to increase its height and become visible to the earth's surface is called an Island.

This is how a volcanic eruption causes the formation of a new island by interacting geosphere and hydrosphere. So, the correct option is (d).
