Question 237614: The ratio of two supplementary angles is 4:5. What is the measure of the smaller angle? (Supplementary means the angles have a sum of 180). Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Let (180 - x) = smaller angle
Let x = bigger angle
Then 4x + 5x = 180
9x = 900
x = 900/9
x = 100
The bigger angle is 100.
Smaller angle = 180 - 100 or 80.
