If a chord `AB` subtends and angle of `60^(@)` at the centre of a circle, then the angle between the tangents to the circle drawn from `A` and `B` is

Explanation

To solve the problem, we need to find the angle between the tangents to the circle drawn from points A and B, given that the chord AB subtends an angle of 60 degrees at the center of the circle (O).

### Step-by-Step Solution:

1. **Identify the Given Information**:
- Chord AB subtends an angle of 60 degrees at the center O of the circle.
- We need to find the angle ACB, where C is the external point from which tangents AC and BC are drawn to the circle.
