let the two angles be 4x and 5x (notice they are in the ratio 4:5)
but they are supplementary, so
4x + 5x = 180
9x = 180
x = 20
making 4x = 80, and 5x = 100
so the larger of the two angles is 100ยบ
What is the number of degrees in the measure of the larger of two supplementary angles if the ratio of their measure is 4:5?
