Please tell me the answer,urgently nedded

Answer 1

Answer:

126 degree

Step-by-step explanation:

a+b+90=180

2x+3x+90=180

5x=90

x=18

a=36

b=54

b=o

54+c = 180

c = 126

Answer 2

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
