Question

Two parallel lines are crossed by a traversal. What is the value of h?

h=60
h=80
h=100
h=120

Answer 1

h=60

Explanation:

The angle that is 120 degrees and the angle that is h degrees are called same side interior angles

Same side interior angles are supplementary, meaning that they add to 180 degrees

To find h we can use Measures addition postulate to find the unknown value h

h+120=180

h=60
