Question

In the picture below, angle 2 = 130 degrees, what is the measurement of angle 1?

Answer 1

It’s b, 50 degrees because a straight line is 180 degrees, so you just subtract 130 from 180 and it gives you 50.

Answer 2

50°

Explanation:

`\angle 1` and
`\angle 2` form a linear pair, and are thus supplementary (meaning they add to 180°).
