Question

Ratio of two angle of linear pair is 2 ratio 3 find the angle

Answer 1

2x + 3x = 180
5x = 180
x = 180/5
so x = 36
2x = 36*2 = 72
3x = 36*3 = 108
You can verify this by adding both the angles
you will get 180
then your answer is correct

Answer 2

let us take 2:3 as 2x and 3x then

2x+3x=180[linear pair forms 180]

5x=180

x=180/5

therefore,x=36
