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

THANK YOU SOOOO MUCH. :)
