Find the value of X in the given figure:
120
60
0
30
As ∠AOB = ∠DOE (vertically opposite angles)
Vertically opposite angles are equal.
So, ∠X = 60∘
In the given figure,O is the centre of the circle. If∠ACB=60∘then find ∠OAB.
In the given figure, LMN is tangent to the circle with centre O. If ∠ PMN = 60∘, find ∠ MOP.
