Answer:
Angle c = 126º
Explanation:
Given :
- ∠POY = 90
- a:b=2:3
To Find :
- ∠c
Solution :
Let the common ratio between a and b be 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
