Question 349140: the measure of the supplement of an angle is 20 degrees more than 3 times the measure of the original angle. What are the measures of the angles? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! HI,
*Note: the sum of supplementary angles is 180 degrees
Let x be the "original" angle would be the other
.
.
simplify and solve for x
.
x = 40 degrees
(3x+20) = 140
.
check Your answer:
40degrees + 140degrees = 180degrees
