Question

Please tell the answer with all of the explaination

Answer 1

Step-by-step explanation:

IN TRIANGLE PQR-

SINCE, PQ=PR

THEREFORE, PQR=PRQ

ANGLE(PQR+PRQ+QRP) = 180°

2PQR = 180°-QPR

2PQR = 180°-50°

2PQR = 130°

PQR = 65° HENCE, PRQ IS ALSO 65°

IN TRIANGLE SQR-

SQ=SR

THEREFORE, SQR=SRQ

ANGLE QSR = 80°

SQR+SRQ+QSR = 180°

2SQR = 180°-QSR

2SQR = 180°-80°

2SQR = 100°

SQR = 50° HENCE, SRQ IS ALSO 50°
