Let the measure of the angle be x o. Its complement will be (90 o - x o) and its supplement will be (180 o - x o). Supplement of thrice of the angle = (180 o - 3x o) According to the given information: (90 o - x o) = (180 o - 3x o) 3x - x = 180 - 90 2x = 90 x = 45. Thus, the measure of the angle is 45 o. The measure of the angle is 45 o
