Two parallel lines are crossed by a transversal what is the value of m

Option C. m = 102°

Step-by-step explanation:

In this question two parallel lines are given as e and f and d is the transverse.

Given angles m and 79° are the interior angles on the same side of the transverse.

According to the theorem

if two lines e and f are parallel and line d is intersecting these lines, interior angles on the same side of transverse (angle m and 78°) will be supplementary angles.

m + 78° = 180°

m = 180° - 78°

m = 102°

Therefore, Option C. m = 102° is the answer.
