Explanation:
Correct option is
B
60
∘
PQRS is a cyclic quadrilateral.
Then, ∠PQR+∠PSR=180
∘
…[Opposite angles of cyclic quadrilateral are supplementary]
⟹ ∠PQR+150
o
=180
∘
⟹ ∠PQR=180
∘
−150
∘
=30
∘
.
In △PQR,
∠PRQ=90
∘
(Angle of a semicircle)
Then, ∠RPQ+90
∘
+30
∘
=180
∘
…[Angle sum property]
⇒∠RPQ+120
∘
=180
∘
⇒∠RPQ=60
