In the given figure, PQ = PS and QR = RS. The measure of QPS is 230 and PQR is 25. What is the measure of QRS? Share with your friends Share 0 Manbar Singh answered this In △ PQR and △ PSRPQ = PS givenQR = RS givenPR = PR given∴ △ PQR ≅ △PSR SSS⇒ ∠PQR = ∠PSR CPCT⇒ ∠ PSR = 25°Also, ∠QPR = ∠SPR CPCT .............1Also, ∠QRP = ∠SRP CPCT ..............2Now, ∠QPS = 230°⇒ ∠QPR = ∠SPR = 12 × 230° = 115° Using 2In △ PQR,∠QPR + ∠PQR + ∠QRP = 180° Angle Sum Property⇒ 115° + 25° + ∠QRP = 180°⇒ ∠QRP = 180° - 140° = 40°⇒ ∠SRP = 40° Using 2Now, ∠QRS = ∠QRP + ∠SRP = 40° + 40° = 80° 0 View Full Answer Shubham answered this whats the answer 0 Shubham answered this check the question again 0
