 Question 626941: the measure of an angle is 30 degree more than twice the measure of its supplement. Find the measures of the angles. Answer by psbhowmick(529)   (Show Source): You can put this solution on YOUR website!Let the angle be X degree. Then its supplement is (180-X) degree. Given that, Angle - 2 x Supplement = 30. X - 2(180 - X) = 30 X - 360 + 2X = 30 3X = 30 + 360 = 390 X = 390/3 = 130 Hence, the angles are 130 and 50 degrees.
