Answer:
On line xoy ray po stands so
angle pox+angle poy=180°
a+b+90°=180°
2x+3x=180-90
5x=90°
x=18
now 2x=2×18=36
3x=3×18=54
MN is a straight line where ray ox stands
xom+xon=180
b+c=180°
54+c=180°
c=180°-54°
C=126°...

Answer:
If ∠POY=90, then ∠POX=90
∘
∠POX=a+b
It is given that,
b
a
=
3
2
⇒a=
3
2
b
∴
3
2
b+b=90
⇒
3
5
b=90
⇒b=18×3=54
∘
For the value of ∠XON, as we can see
∠XON+b=180
∘
⇒∠XON=126
