Answer:
Step-by-step explanation:
a : b = 2 : 3
so a = 2x , b = 3x
a+b = 5x = 90
x = 18
so a = 36 , b= 54
MN is a straight line so b + c = 180
so c = 180 - 54 = 126

Answer:
Step-by-step explanation:
Given,
∠POY
= 90° &
a : b = 2 : 3
∠POY+∠POX =180°
a + b = 180°
⇒90° + a + b = 180°
⇒a + b = 90°
Let a = 2x & b= 3x
2x + 3x = 90°
⇒5x = 90°
⇒x = 18°
∴a = 2×18° = 36°
b = 3×18° = 54°
Now, OX is a ray on the line MON.
∠XOM+ ∠XON=180°
b + c = 180° (by Linear Pair axiom)
⇒54° + c = 180°
⇒c = 126°
The value of c =126°
