1.	If PQRS is a parallelogram in which anglePQR is 75° and angle PRS is 60° find angle P
Answer» $PQRS \:is \:a \: parallelogram . \\PQ\parallel SR \:and \: \\PS\parallel QR ,\\\angle {PQR} = 75\degree$ $\red { To \:find : } \\\angle P = ?$ $\angle P + \angle {PQR} = 180\degree$ $\pink { ( Sum \: of \: adjacent \:angles \:are }$ $\pink { supplementary .) }$ $\implies \angle P + 75 \degree = 180\degree$ $\implies \angle P = 180\degree - 75\degree\\= 105\degree$ THEREFORE., $\red {\angle P}\green {= 105\degree }$ •••♪
