Question

PLEASE HELP!!

Find the value of x.
X
(5x + 15)
55°
A. 8
B. 14
C. 4
D. 22

Answer 1

A

Explanation:

both angles must be the same. as also the top and the bottom angles are identical to each other.

that is how crossing lines work. if they would change the angles after the intersection point, they would no longer be the straight extensions of the lines going "into" the intersection.

so,

5x + 15 = 55

5x = 40

x = 8

Answer 2

A since 5(8) + 15 = 55
