You can
put this solution on YOUR website!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)
