 Question 414921: Two angles are supplementary and one is 40 degrees more than three times the other. find the smaller angle.Answer by praseenakos@yahoo.com(507)   (Show Source): You can put this solution on YOUR website!supplementary angles add up to 180 degrees let the smaller angle be x degrees then the other is 3x + 40 degrees their sum should be 180 degrees so x + 3x + 40 = 180 ==> 4x + 40 = 180 ==> 4x = 180 - 40 ==> 4x = 140 degrees ==> degrees ==> x = 45 degrees smaller angle is 45 degrees
