Triangle A'B'C' is a reflection of triangle ABC across line BC. Prove that ray BC is the angle bisector of angle ABA'.​

Answer:

Skew

Step-by-step explanation:

I took it on edge 2020

Line AC and RS are in different plane and they do not intersect, hence they are skew lines.

A point is a location and it has no magnitude. A line is defined as something that extends infinitely in either direction. A line is the shortest distance between two points.

Skew lines are two lines that do not intersect and are not parallel. Hence the two lines do not exist in the same plane.

Line AC and RS are in different plane and they do not intersect, hence they are skew lines. They are not parallel also.

The value of y is 48.

To find the value of y in this scenario, we need to use the fact that the angle bisector of ∠JSL splits it into two congruent angles.

Let's denote one of these congruent angles as ∠HSL and the other as ∠LSJ. Since ∠JSL is bisected, we have:

m∠JSL = m∠HSL + m∠LSJ

Given that m∠JSL = (4y - 10)° and m∠HSL = m∠LSJ = ∠HSJ = (y + 43)°, we can substitute these values into the equation:

4y - 10 = (y + 43) + (y + 43)

Simplifying the equation:

4y - 10 = 2y + 86

Subtracting 2y from both sides:

2y - 10 = 86

Adding 10 to both sides:

2y = 96

Dividing both sides by 2:

y = 48

Therefore, the value of y is 48.

Answer:

For x = 10, the lines will be parallel

Step-by-step explanation:

For parallel lines in a triangle, their sides must be proportional

And,

\(\frac{x+4}{x-3} = \frac{x+10}{x}\)

Cross Multiplying

=> x(x+4) = (x-3)(x+10)

=> \(x^2+4x = x^2+7x-30\)

=> \(x^2-x^2+7x-4x = 30\\\)

=> 3x = 30

The volume of the cylinder would be 2120.6\(units^3.\)

To find the volume of a cylinder, you need to use the formula:

Volume = π x \(radius^2\) x height

Where π (pi) is a mathematical constant approximately equal to 3.14159, radius is the distance from the center of the cylinder to its edge, and height is the distance from one end of the cylinder to the other.

To apply this formula, you need to know the values of the radius and height of the cylinder. Once you have these values, simply substitute them into the formula and solve for the volume.

For example, if the radius of a cylinder is 5 units and the height is 27 units, the volume of the cylinder would be:

Volume = π x \(radius^2\)x height

Volume = 3.14159 x\(5^2\)x 27

Volume = 2120.6 \(units^3\)

Therefore, the volume of the cylinder would be 2120.6\(units^3.\)

The probability that the coin shows heads and the die shows an odd number is 1/4 or 0.25, which can also be expressed as 25% or 0.25 in decimal form.

To determine the probability that a coin shows heads and a die shows an odd number, we need to consider the individual probabilities of each event and then multiply them together.

1. The probability of the coin showing heads is 1/2, as there are two equally likely outcomes (heads or tails) and only one of them is heads.

2. The probability of the die showing an odd number is 3/6, or 1/2, since there are six equally likely outcomes when rolling a fair six-sided die, and three of them (1, 3, and 5) are odd numbers.

To find the probability of both events occurring, we multiply the probabilities: (1/2) * (1/2) = 1/4.

Answer:

Step-by-step explanation:

1) 5x + 4 + 3x - 8 = 180 ( co - interior angles )

8x - 4 = 180

8x = 184

x = 184 / 8

x = 23°

y = 3x - 8 ( vertically opposite angles )

y = 3 × 23 - 8

= 69 - 8

= 61°

4) 5 x + 7 = 2x + 97 ( vertically opposite angles )

5x - 2x = 97 - 7

The length of the diameter of the sphere is 30 cm.

The surface area of a sphere is given by the formula:

\(A = 4\pi r^2\)

where A is the surface area and r is the radius of the sphere.

We are given that the surface area of the sphere is 900π cubic cm. Therefore:

\(A = 4\pi r^2 = 900\pi\)

Dividing both sides by 4π, we get:

\(r^2 = 225\)

Taking the square root of both sides, we get:

r = 15

The diameter of the sphere is twice the radius, so:

d = 2r = 30

Therefore, the length of the diameter of the sphere is 30 cm.

A model of a car is 4 inches long.

The actual car is 10 feet long.

 4 in. = 10 ft. ( since given )

Divide both sides by 4, we get

We use the ratio here to compare the lengths of the actual car and its model.

A ratio scale is a quantitative measurement scale that is used to compare numbers.

The model is 4 inches long while the actual car is 10 feet long.

One foot is equal to 12 inches. Therefore the car in terms of inches is:

10 feet × 12 inches = 120 inches

The ratio scale is the length of the model of the car : length of the actual car

The actual area of the field in square kilometers is \(30000000 km^2\)

Step-by-step explanation:

Scale : 1 cm = 50000 km

Area of field on map = \(1.2 cm^2\)

Now , 1 cm = 5000 km

\(1 cm^2 = (5000 km)^2\)

We are supposed to find the actual area of the field in square kilometers.

So, the actual area of the field in sq. km =\(1.2 \times (5000)^2\)

Actual area of the field in sq. km \(=30000000 km^2\)

Hence the actual area of the field in square kilometers is \(30000000 km^2\)

The distance between point T (-5, 1) and point I (-1, 1) is 4 units.

To find the distance between two points, we can use the distance formula, which is derived from the Pythagorean theorem. The formula is:

Distance = √((x2 - x1)² + (y2 - y1)²)

Let's apply this formula to find the distance between point T (-5, 1) and point I (-1, 1):

x1 = -5, y1 = 1 (coordinates of point T)

x2 = -1, y2 = 1 (coordinates of point I)

Plugging these values into the formula, we have:

Distance = √((-1 - (-5))² + (1 - 1)²)

        = √(4² + 0²)

        = √(16 + 0)

        = √16

        = 4

Therefore, the distance between point T (-5, 1) and point I (-1, 1) is 4 units.
