Answer:

50

Step-by-step explanation:

angle N=65(by parallel lines)

angle M=65(by cyclic quadrilateralMQPN)

R+M+N=180

N=50

\angle R=50^{\circ}

Step-by-step explanation:

In triangle RMQ

NP is parallel to MQ

MN=QP

By triangle proportionality theorem

\frac{RN}{NM}=\frac{RP}{PQ}

\frac{RN}{PQ}=\frac{RP}{PQ}

RN=\frac{RP\times PQ}{PQ}=RP

MN=QP

RN=RP

RN+NM=RP+PQ

RM=RQ

Angle M=Angle Q=65 degrees

Angle made by two equal sides are equal.

In triangle RMQ

\angle R+\angle M+\angle Q=180^{\circ}

By using triangle angles sum property

Substitute the values then we get

\angle R+65+65=180

\angle R+130=180

\angle R=180-130=50^{\circ}

\angle R=50^{\circ}
