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

I added the diagram of the question.


h = 60°

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 :)

The correct answer would be "convenience"

Ask google i believe they can you with that question
