Question

If angle 1 and angle 2 form a linear pair and m angle 1 = 72°, find m angle 2.

Answer 1

Well since it's a linear pair it equals to 180 degrees. So if angle 1 is 72 degrees, all you have to do to find angle 2 is subtract 72 from 180, and you have 108 degrees.

Answer 2

180-72 is the answer. D. 108
