Question

Please tell me the solution

Answer 1

Step-by-step explanation:

QPR +PRQ+RQP=180

30+90+RQP=180

RQP=180-120

RQP =60

RQP-RQS =180

60-RQS=180

RQS =180-60

RQS = 120

Answer 2

Answer:

RQS=129°

Step-by-step explanation:

In triangle PQR,

PQR+PRQ+QPR=180° (Angle Sum Property of a triangle)

PQR+90°+30°=180°

PQR+120°=180°

PQR=180°-120°

PQR=60°

PQR+RQS=180° (Linear Pair)

60°+RQS=180°

RQS=180°-60°

RQS=120°
