Hi pupil here's your answer ::

_____________________________

Since ray OP stands on line XY Therefore

➡POY + POX = 180°

➡90° POX=180°

➡POX = 180-90 = 90°

▶ a+ b = 90°
but
●a:b = 2 : 3

sum of ratios ÷ 2 + 3 = 5

✔a=
$\frac{2}{5} \: \times 90 = 36$

✔b=
$\frac{3}{5} \times 90 = 54$

Now MN is a line
OX stands on MN
Therefore,

✴MOX + XON = 180°

✴b + c = 180°

✴ 54° + c = 180°

✴c = 180-54 = 126°

✴c = 126°
