Question

Find the value of x in each case. A B E ​

Answer 1

18

Explanation:

Consecutive interior angles are supplementary, therefore 180 - 8x = angle C.

Alternate interior angles are congruent, so angle C is equal to 2x.

180 - 8x = angle C

Substitute angle C with 2x

180 - 8x = 2x

180 = 10x

x = 18
