Question

two angles of a linear pair are in the ratio of 3:5 find the angles

Answer 1

the angles are 135/2 and 225/2

Answer 2

Let the angles be 3x and 5x
We know that the sum of linear pair is 180'
3x + 5x = 180
8x =180
x=180/8
x = 22.5

3x= 3 x 22.5
3x = 67.5

5x = 5x22.5
5x = 112.5

67.5 and 112.5 are 2 angles
