Question

What is the measurement, in degrees, of angle h?

Answer 1

180•=130•+h
h=180-130
h=50 degrees

Answer 2

50º

Explanation:

We can see that h and the the 130º angle form a supplementary angle. This means that the two angles are equal to 180º. So, we can turn this into an algebra problem: x + 130º = 180º. So, if we solve this equation we find that x = 50º.
