Angle BOC = 120°.

Step-by-step explanation:

Given:

In given figure, AOC is a diameter of the circle

arc AXB = \frac{1}{2}\timesarc BYC

We know that, central angle is always equal to its opposite arc  

Therefore ∠AOB = \frac{1}{2}\times ∠BOC  (1)

Also,  ∠ AOB + ∠BOC =  180° [linear pair  axiom]

\frac{1}{2}\times \angle BOC + \angle BOC = 180\°     [from equation 1]

\frac{\angle BOC +2 \angle BOC}{2}=180\°

\frac{3 \angle BOC}{2} =180\°

∠BOC = \frac{180\times2}{3}

∠BOC  = \frac{360}{3}

Hence  ∠BOC = 120°.
