Question

Two parallel lines are crossed by a transversal.What is the value of m?

Answer 1

Same side interior angles are supplementary, which means together they add up to 180 degrees.

In order to find the value of angle m, subtract 180 from the supplement.

180 - 78 = 102

The value of m is 102 degrees

Answer 2

C.m=102

Explanation:

The two angles are alternate interior angle, those angles add up to 180, 180-78=102. The answer is c
