Question

lines X .y and MN intersect at O .if PoY =90° and a:b=2:3,fin
d C
​

Answer 1

Solution :-

Given :-

∠ POY = 90°

∠ POX = 90°

a + b = 90° ... 1

Given :-

a/b = 2/3

a = 2x

b = 3x

Put in 1

➻ 2x + 3x = 90°

➻ 5x = 90°

➻ x = 18

➻ a = 2 × 18

➻ a = 36

➻ b = 3 × 18

➻ b = 54

➻ b + c = 180°

➻ 54 + c = 180°

➻ c = 180° – 54°

➻ c = 126°

hope it helps.
