The value of ∠EOF is 75°.

Explanation:

Let us take O be the center of the circle.

Given,

∠AOB = 45°

∠COD = 60°

To find the ∠EOF (value of x)

Now,

Since AD is the diameter of the circle, ∠AOD = 180°

∠AOB+∠COD+∠BOC = ∠AOD

Or, 45°+60°+∠BOC = 180°

or, ∠BOC = 180°-(45°+60°)

= 75°

Again,

∠BOC = ∠EOF as they are vertically opposite angle.

Hence,

∠EOF = 75°
