Question 168076: the sum of twice the supplement of an angle and three times its compliment is 711 degrees. What is its angle? Answer by bhembhe(4) (Show Source):
You can put this solution on YOUR website! x-> angle
180-x -> supplement
90-x -> complement
working equation:
2(180-x) + 3(90-x) = 711
360-2x+270-3x = 711
-5x+ 630 = 711
-5x = 81
x = -16.2 degrees
