The diameter of the circle is PQ.

R is a point on the circumference of the circle.

Angle PQR = 30o (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
