Answer:
A.
Step-by-step explanation:
If the results are similar (A) should be your answer!
180-40=140. 140/5 = 28
x= 28
angle B: 5(28) = 140
140 + 40 = 180
180=180
The area of the circle can be calculated with the following formula

First let's find the radius


The answer would be 200.96 square yards
Answer:
Step-by-step explanation: write the equation in the form of a proportion
2 1/2 is to 4 as something is to 3
2 1/2 / 4 = x/3
Then, cross multiply 2 1/2 x 3 or
5/2 x 3/1 = 15/2
Next cross multiply 4•X= 4X
Write as 4X = 15/2
Divide both sides by 4.
4X/ 4 = 15/2 /4
x = 15/2÷ 4/1
Divide by changing the sign to multiplication and inverting 4/1 to 1/4 like this:. 15/2. × 1/4= 15/8
Finally, 15/8 simplifies to 1 7/8 cups
