Question

two angle forming linear pair are in the ratio 2:7. find the angle​

Answer 1

Let the angle be 'x'

The sum of linear pair is = 180

2x + 7x = 180

9x = 180

x = 180/9

x=20

The angles are:- 2 x 20 = 40

:- 7 x 20 = 140

So, the angles are 40 and 140 degree

Answer 2

Step-by-step explanation:

Let the angle be x .

°•° both angles forming linear pair in ration 2:7

•°• 2x+7x = 180

=> x = 20°

Hence angle is 2×20° = 40° and 7×20 = 140°
