The triangles below are congruent and their corresponding parts are marked
∠A ≅ ∠Z
you can determine this by seeing that both angles have two curved lines, therefor showing they have the same measurement.
∠B ≅ ∠Y
you can also determine this by seeing that they both have one curved line showing that they share the same measurement.
∠C ≅ ∠X
once again, you can determine this by seeing that both angles are marked with three curved lines, meaning they share the same measurements.
line AB ≅ line ZY
just like before, you can determine that they are equivalent to each other by seeing that both lines have three dashes showing that they have the same measurement.
line AC ≅ line ZX
you can determine these lines are equivalent because they both have one dash showing they are the same length as each other.
line BC ≅ line YX
once again, both lines have two dashes, showing that they are equivalent in length.
ΔCAB ≅ XZY
you can determine this by seeing that all three angles and all three sides on both triangles share measurements with the other triangle
Bob is 4 years younger than Ann and 5 years older than Frank. Alice is with 20 years 5 years older than Frank. What's the age difference (in years) between the oldest and youngest person
Given :
Bob is 4 years younger than Ann and 5 years older than Frank. Alice is with 20 years 5 years older than Frank.
To Find :
The age difference (in years) between the oldest and youngest person.
Solution :
Let, age Bob is x.
Age of Ann = x + 4.
Age of Frank = x - 5.
Age of Alice = 20 .
It is given that Alice is 5 years older than Frank.
x - 5 = 20 - 5
x = 20
So, age of Ann = 20 + 4 = 24
Age of Bob = 20
Age of Frank = 15
Therefore, age difference between oldest and youngest person is 24 - 15 = 9 years.
Hence, this is the required solution.
The age difference (in years) between the oldest and youngest person is; 9 years
Let the age of Bob be x.
Now, Bob is 4 years younger than Ann and 5 years older than frank. Thus;
Age of Ann = x + 4
Age of Frank = x - 5
Alice is 20 years old and 5 years older than frank. Thus;
Age of Alice = 20
Age of frank = 20 - 5 = 15 years
From earlier, we saw that age of frank = x - 5
Thus;
x - 5 = 15
x = 15 + 5
x = 20 years
Thus;
Age of Ann = 20 + 4 = 24 years
We have established that;
Age of Bob = 20 years
Age of Frank = 15 years
Age of Ann = 24 years
Thus, oldest is Ann at 24 years old
Youngest is frank at 15 years
Thus, age difference between oldest and youngest person is; 24 - 15 = 9 years.

For a $200,000 mortgage, with an interest rate of 4% paid over 20 years, the monthly payment is $1,211.96. After one month, what is the balance of the loan? Give your answer to the nearest dollar.
The balance on the loan will be $198,908.
Based on the information given, the amount of interest for the first month will be:
= $200,000 × 0.0412
= $666.67
During the first month, the amount subtracted from the loan will be:
= $12111.96 - $666.67
= $545.29.
The interest accrued for the second month will be:
= $199454.71 × 0.0412
= $664.85
Therefore, the balance on the loan after the second month will be:
= $199454.71 - $547.11

1. Joshua has a ladder that is 12 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 11.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 75°. Will the ladder be safe at this height? Show your work and draw a diagram to support your answer.
Answer:
So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).
That angle ladder makes with the ground = €
SOH: sin € = opposite/hypotenuse
No the ladder won't be safe!!!
Now let's make it safe:
The ladder's length (w) is constant, so stays 12
So now let's ask in an inequality what height will be safe (75° or less)
what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!

Answer:
h = 1,268 cm
Step-by-step explanation:
V = (π·r²·h)/3, general formula
83 = (π·4²·h)/3, substitute what is given V= 83 cm³ and r = 4 cm
83 ·3 = (π· 16·h)·3/3, multiply both sides by 3 and solve 4² = 16
249 = π·16·h, multiply 83·3 = 249 and 3/3 = 1
249/ π·16 = h , divide both sides by π·16
1,268.146587 = h, solve
1,268 ≈ h , is rounded to the nearest cm

To find A U B, we have to write all numbers that are in A and/or in B. The number that are in both sets must not be written again.
A U B = {2, 3, 6, 4, 5, 7}
Writing then in acending order:
A U B = {2, 3, 4, 5, 6, 7}
Answer: A U B = {2, 3, 4, 5, 6, 7}.
A middle school took all of its 6th grade students on a field trip to see a ballet. The students filled 1898 seats, which was 73% of the total number of seats in the theater. How many total seats were in the theater?
Answer:
x = 2600 seats.
Step-by-step explanation:
Let the total number of seats be x.
Given the following data;
Number of seats occupied = 1898 seats
Percentage = 73%
To find the total number of seats;
Translating the word problem into an algebraic equation, we have;
\( \frac {73}{100} * x = 1898 \)
Cross-multiplying, we have;
\( 73x = 1898 * 100 \)
\( 73x = 189800 \)
\( x = \frac {189800}{73} \)
x = 2600 seats.
Therefore, the total number of seats in the theater are 2600 seats.

What is the length of PQ?
14 units
17 units
27 units
34 units
The length of the line segment AB is 5 units.
Unfortunately, you haven't provided any information about PQ such as its location or any other data to help solve the question.
Therefore, it's impossible to determine the length of PQ using the given options. However, here is an explanation of how to find the length of a line segment using the distance formula, which may help you in solving similar questions in the future.
The distance formula is used to find the distance between two points in a coordinate plane, such as the length of a line segment. The formula is:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
where d is the distance, (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
To use the distance formula, you first need to find the coordinates of the two points that make up the line segment. Then, substitute these coordinates into the formula and simplify to find the distance.
For example, let's say you have two points: A(1, 2) and B(4, 6), and you want to find the length of the line segment AB. Using the distance formula:
d = √((4 - 1)² + (6 - 2)²)
d = √(3² + 4²)
d = √(9 + 16)
d = √25
d = 5
Remember, the distance formula can be applied to any two points in a coordinate plane to find the distance between them.

A rental car company charges $22 per day to rent a car and $0.08 for every mile driven. Samuel wants to rent a car, knowing that:
He plans to drive 450 miles.
He has at most $80 to spend.
Write and solve an inequality which can be used to determine xx, the number of days Samuel can afford to rent while staying within his budget.
Using the inequality concept, the expression models the number of days Samuel can afford to rent while staying within his budget is 11x + 18 ≤ 40
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
A rental car company charges $22 per day to rent a car and $0.08 for every mile driven
The maximum amount to spend = $80
Fixed charge per day $22
Charge per mile = $0.08
The inequality which represents the number of days Can be expressed thus :
(Charge per day × number of days) + (charge per mile × number of miles) ≤ 80
22x + 0.08× 450 ≤ 80
22x + 36 ≤ 80
Divided by 2 both sides of an inequality,
11x + 18 ≤ 40
Hence, the required inequality expression is 11x + 18 ≤ 40

Which equation is perpendicular to the given one?A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Two lines are perpendicular if the product between the slopes is -1.
Here we want to find a line perpendicular to:
2x + 3y = 10
We can rewrite this as:
3y = 10 - 2x
y = (10/3) - (2/3)*x

An angle measures 8° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
41° and 49°
Step-by-step explanation:
Complementary angles are angles that sum up to 90°.
Let x represent the smaller angle, then the bigger angle will be represented with x + 8:
x + x + 8 = 90°
Add like terms.2x + 8 = 90°
Subtract 8 from both sides.2x = 82°
Divide both sides by 2.x = 41° this is the measure of smaller angle, then the bigger angle wpis 49°
The answer is:
⇨ 41 and 49Work/explanation:
If two angles are complementary, their measures add to 90°.
So we can set up an equation to find the angles. Let the unknown angle be w, and its complement will be w + 8:
w + w + 8 = 90
Combine like Terms
2w + 8 = 90
2w = 82
w= 41
The other angle measures 8° more than the measure of w:
41 + 8 = 49
Hence, the angles are 41 and 49°.
