If TP and TQ are the two tangents to a circle with centre O so that `/_P O Q=110^@`, then `/_P T Q` is equal to

Explanation

To solve the problem, we need to find the angle \( \angle PTQ \) given that \( \angle POQ = 110^\circ \) and that \( TP \) and \( TQ \) are tangents to the circle at points \( P \) and \( Q \) respectively.

### Step-by-Step Solution:

1. **Identify the Given Information:**
- We have a circle with center \( O \).
- \( TP \) and \( TQ \) are tangents to the circle at points \( P \) and \( Q \).
- The angle \( \angle POQ = 110^\circ \).
