Step-by-step explanation:
Given, PQ is a chord of a circle with center O.
Also, ∠QPT=60°.
Let x be the point on the tangent PT.
∠QPT+∠OPT=90
⇒∠OPT=300−∠QPT=900−600=300
In ΔPOQ
∠POQ=180−(∠OPQ+∠PQO)=180−30−30=1200
Minor arc ∠POQ=1200
Therefore Major arc ∠POQ=3600−1200=2400
Angle subtended by an arc at centre is double the angle subtended by it on remaining part of circle
∴∠QRP=21∠POQ=1200
