We know that the Angle subtended by an arc on centre of the circle is double as that of Angle subtended by the same arc on the circumference (boundary) of the circle

So,

$\sf \angle MCP = 2\angle MRP$

$\sf65 \degree = 2 \angle MRP$

$\sf\angle MRP = 65 \degree \div 2$

$\sf\angle MRP = 32.5 \degree$
