Answer: (2). 60 degree.

The diameter of the circle is PQ.

R is a point on the circumference of the circle.

Angle PQR = 30^o (given)

As we know that angle sustained on the circumference of circle is 90⁰

On joining points P, Q, R It forms a Triangle PQR.

In Triangle PQR,

Angle (RPQ) + Angle (PQR) + Angle (PRQ) = 180⁰ (Angle sum property of triangle)

Angle (RPQ) + 30⁰ + 90⁰ = 180⁰

Angle (RPQ) = 180⁰ – 120⁰

Angle (RPQ) = 60⁰
