the mesaure of the supplement of an angle is 20 degrees more than three times the measure of the original angle. Find the measures of the angles.
-----------------------
Let the measure of the angle be "x".
Its supplement is "180-x".
EQUATION:
180-x -20 = 3x
160 = 4x
x = 40 degrees (original angle)
180-x = 140 degrees (its supplement)
