Answer:

A = 17.5 in^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) *h

b1 = 4 in

b2 = 3 in

h = 5 in

A = 1/2((4+3) *5

A = 1/2(7)*5

A = 1/2(35)

A = 17.5 in^2

Anyone know the answer?

vodomira [7]

To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R

7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5

Angle R = 12x + 20
12(5) + 20
60 + 20
80

Option C is your answer.
