Question

Two parallel lines are crossed by a transversal. What is the value of h? h = 60 h = 80 h = 100 h = 120

Answer 1

A. h = 60

Step-by-step explanation:

Answer 2

I added the diagram of the question.

Answer:
h = 60°

Step-by-step explanation:
We are given that lines k and l are parallel lines.
This means that angles 120° and h are supplementary angles.
This means that their measures add up to 180°

Therefore:
180° = 120° + h
h = 180° - 120°
h = 60°

Hope this helps :)
