31. Find the measure of an angle that is 30o less than its supplement. 32. Find the measure of an angle that is one-half the measure of its complement. 33. Find the measure of an angle that is one-half the measure of its supplement. (x) + (x – 30) = 180 2x – 30 = 180 2x = 210 x = 105 The angle is 75o. x (x – 30)o o (x) + (2 1 x) = 90 1.5x ... ................
