Question

Two supplementary angles have a ratio of 4:5 what is the measure of the larger angle?​

Answer 1

100°

Explanation:

Supplementary means the sum of the angles is 180°

so we add 4+5 = 9

180/9 = 20

20 now we multiply according to the ratio

20x4:20x5

80:100

the measure of the largest is 100°
