hello mate

Let the common ratio between a and bbe x.

∴ a = 2x, and b = 3x

XY is a straight line, rays OM and OP stand on it.

∴ ∠XOM + ∠MOP + ∠POY = 180º

b + a + ∠POY = 180º

3x + 2x + 90º = 180º

5x = 90º

x = 18º

a = 2x = 2 × 18 = 36º

b = 3x= 3 ×18 = 54º

MN is a straight line. Ray OX stands on it.

∴ b + c = 180º (Linear Pair)

54º + c = 180º

c = 180º − 54º = 126º

∴ c = 126º

Thanks for questioning

Answer:

let a=2x

b= 3x

2x+3x+ 90= 180°( linear pair)

5x=90

x=90/5

=18

a=2×18

= 36

b=3×18

=54

54+c=180(linear pair)

c=180-54=126.
