In the diagram, If < RPS = 50^o, < RPQ = 30^o and pq = QR, Find the value of < prs

50^o

60^o

70^o

80^o

Correct answer is C

< QPR = < PRQ = 30^o (PQ = QR)

< SPQ + < QRS = 180^o (supplementary)

80 + < QRS = 180^o = < QRS = 180^o - 80^o = 100^o

< QRP + < PRS = 100^o = 30^o + < PRS = 100^o

= < PRS = 100^o - 30^o = 70^o
