You can represent the measures of an angle and its complement as x° and (90 − x)°. similarly, you can represent the measures of an angle and its supplement as x° and (180 − x)°. use these expressions to find the measures of the angles described. the measure of an angle increased by 26° is equal to the measure of its complement. the measure of the angle is ° and the measure of its complement is °.
