Question

two supplementary angles are in ratio 2:7 find the measure of angle ​

Answer 1

Answer:

Supplementary = 180 degree

2:7 = 180

2x + 7x = 180

9x = 180

x = 180/9 = 20

2x = 2 × 20 = 40

7x = 7 ×20 = 140

Answer 2

Answer:

given that ratio of supplementary angles is 2:7

so sum of supplementary angles is 180

first angle is 2/9x180

=360/9

=40°

so other angle is 180-40=140°
