Question 496716: angle c and angle d are supplementary. The measure of angle d is eight times the measure of angle c. find the measurments of angle c and angle d Answer by cleomenius(959) (Show Source):
You can put this solution on YOUR website! x + 8x = 180.
9x = 180.
x = 20 degrees. This is our smaller angle.
8(20) = 160 degrees. This is our larger angle.
20 + 160 = 180 degrees.
This does check.
