Four of the angles of a pentagon measure 85°, 110°, 135°, and 95°. Find the measure of the missing angle.

A - 115°

B - 95°

C - 135°

D - 85°

The answer would be A:115 because the sum of all the angles should add up to 540 so if you add the numbers 85, 110, 135, and 95 you get 425

Then you would subtract that from 540.

540 - 425 = 115
