find the measures of x and y
please helppp!
Answer:
Each angle has a measure of 75 degrees
Step-by-step explanation:
First of all, we know that angle Z has a measure of 120 degrees and that angle W is a right angle. This means that the measure of angle W would have to be 90.
Next, we know that because the shape is a quadrilateral, the sum of its interior angles has to be equal to 360. Since we know that the measure of angles X and Y are equal (by definition of congruent), we will label them both with the variable x. We can then say the following:
2x + 90 + 120 = 360
We can then proceed to simplify this:
2x + 210 = 360
2x = 150
x = 75
So, the measure of x and y are 75.

The Correct option is B.
What is function in Limit ?
Informally, a function f assigns an output f(x) to every input x.
What is the difference between function and limit ?
The value of a function is the actual calculation done at a certain point. The limit is - roughly speaking - the value at points that are “arbitrarily close” to the same point.

The diameter of a circle is 28 inches. What is the circle's circumference
Answer: 87.92.
Step-by-step explanation: To find the circumference of a circle, you need the following equation:
2 x π x r, where π is ≈ 3.14 and r is the circle's radius. If you are ever given the diameter instead of the radius, just cut the diameter in half. In this case, the diameter was given, so we need to cut 28 in half, which makes 14. Your equation should look like this:
2 x 3.14 x 14 ≈ 87.92.

Which expression represents the surface area of the prism?
Answer:
A, 2 · 8 + 2 · 55 + 88
Step-by-step explanation:
If we find the area of the two triangles above and below, we know the area of one triangle is 8 because (formula for area of triangle: a = bh x 1/2, and a = 8(2) x 1/2 which equals 8). So if we double this area, we would get 2 · 8.
If we were to find the area of both the rectangles that are left and right of this figure, we know the area of one rectangle would be 55 because (formula for area of rectangle: a = l x w, and a = 5(11) would equal 55). So if we'd doubled this, we would get 2 · 55.
If we were to find the area of the rectangle in front of this entire figure, we know the area would be 88 because (formula for area of rectangle: a = l x w, and a = 11(8) which would equal 88).
So if we find the surface area of this figure, we'd just need to piece this together to form:-
2 · 8 + 2 · 55 + 88
Answer:
2 · 8 + 2 · 55 + 88

Brainlist A 12" diameter 1-topping pizza costs $8.99. A 14" diameter 1-topping pizza costs $10.99. Which pizza option
gives you more for your money? Justify your answer.
Answer:
The 14" diameter pizza gives you more pizza for your money since it costs less per square inch.
Step-by-step explanation:
We can find the price per square inch of each pizza.
area = πr²
12" diameter pizza
area = π × (6 in.)² = 36π in.²
cost per in.²: $8.99/(36π in.²) = 0.079 $/in.²
14" diameter pizza
area = π × (7 in.)² = 49π in.²
cost per in.²: $10.99/(49π in.²) = 0.071 $/in.²
The 14" diameter pizza gives you more pizza for your money since it costs less per square inch.
