This problem has been solved! Previous question Next question Transcribed Image Text from this Question. Two angles are complementary if their sum is equal to 90° and are supplementary if their sum is equal to 180° Angle 1 + Angle 2 = 130° + 3° Angle 1 + Angle 2 = 133° Since the sum of the two angles ≠ 90°, the two angles are not complementary If the sum of two angles are 180 o then the angles are said to be supplementary angles, . So let's say this the entire half circle or semicircle for a protractor. Answer : Let x be one of the angles… And when you have two angles two angles whose sum add up to 90 degrees, and Start studying Complementary and Supplementary Angles, Geometry. angle that adds up to 90 degrees.
