Question

full solution Please​

Answer 1

Answer:

Step-by-step explanation:

since PQ||RS

construction a AB||PQ||RS and extend SR to Z

therefore after using parallel line properties like corresponding angle and alternating angle

anglePQA+angleAOQ=180

angleAOQ=180-anglePQA

NOW

since AB||SR

angleAOS=angleRSO

angle

Answer 2

Step-by-step explanation:

construction: draw line mo passing through o

Angle PQO+angle QOM =180°

angle PQO+Angle QOS -Angle MOS=180°

Angle PQO + angle QOS=180°+Angle QSR
