The sum of the measures of the three angles of any triangle is 180°. In the illustration, the measure of 2 (angle 2) is 7° larger than the measure of 1. The measure of 3 is 31° larger than the measure of 2. Find each angle measure.

angle 1 = x

angle 2 = x + 7

angle 3 = x + 7 + 31

x + x + 7 + x + 7 + 31 = 180

Solve for x, measure of angle 1.

Then,

angle 2 = x + 7

angle 3 = x + 7 + 31
