PQRS is a quadrilateral in which PQ is parallel to RS, angle PQR is 130 degrees and angle QPS is 75 degrees. Find angle PSR and angle QRS Share with your friends Share 3 Lovina Kansal answered this Dear student Since PQ∥RS. So, PQRS is a trapezium.In trapezium Adjacent angles are supplementary.∴∠P+∠S=180°⇒75°+∠S=180°⇒∠S=105°and ∠Q+∠R=180°⇒130°+∠R=180°⇒∠R=50° Regards 7 View Full Answer S.j. Satish Kumar answered this PSR = 105 degrees QRS = 130 degrees adjacent angles are supplementary as two sides are parallel 0 Girish answered this PSR=105degrees QRS=130degrees 0
