Question

Please tell the answer with explaination

Answer 1

Answer:

Answer: in triangle PQR , PQ = PR so angle PQR = angle prq PQR + PRQ + QPR = 180 a + a + 30 = 180 2a = 180-30 a = 150/2 a = 75 angle PQR = angle PRQ = 75. in triangle SQR , SQ = SR so angle SQR = angle SRQ SQR + SRQ + QSR = 180 b + b + 70 = 180 2b = 180 - 70 b = 110/2 b = 55 angle SQR = angle SRQ = 55.
