Answer:

B. 35°

Explanation:

m<4 = x + 20

m<8 = 2x + 5

✔️First, find the value of x:

m<4 = m<8 (corresponding angles are equal)

Substitute

x + 20 = 2x + 5

Collect like terms

x - 2x = -20 + 5

-x = -15

Divide both sides by -1

x = 15

✔️Find m<8:

m<8 = 2x + 5

Plug in the value of x

m<8 = 2(15) + 5

m<8 = 30 + 5

m<8 = 35°
