Question

Two supplementary angles are in the ratio of 2 : 7, find the angles.​

Answer 1

Answer:

4,14

Step-by-step explanation:

let x be the common ratio

2x+7x= 180

9x=180

x=180/90

x=2

2x=2*2=4

7*2=14

Answer 2

Let the angles be 2x and 7x.

Sum of two supplementry angle =180degree

Therefore, 2x +7x = 180

=> 9x = 180

=> x = 20.

Thus , the two angles are

2×20=40degree

And, 7×20=140degree.
