Question

ratio of two angles of a linear pair is 7 ratio 8 find the angles​

Answer 1

let the angles be 7x and 8x
7x+8x= 180 ( linear pair)
15x = 180
x = 180÷15
x = 12
therefore, 7x = 7×12= 84
8x=8×12=96

Answer 2

Let Angle 1 = 7x

Angle 2=8x

Sum of 2 angles in a linear pair is 180°

Therefore, Angle 1 + Angle 2 = 180°

7x + 8x = 180°

15x = 180°

x = 180°/15

x = 12

7x= 12*7= 84° =angle 1

8x = 12*8=96° = angle 2

84°+96°= 180°
