Question

me given figure, DO, Rand S are the points on the circle with centre CE
POPOR 40 then ZORRIS
O
C) 45
OD) 120​

Answer 1

Reflex ∠POR = 2 × ∠PQR = 2 × 100° = 200°

∴ ∠POR = 360° - 200° = 160°

In ΔOPR,

OP = OR (radii of the circle)

∠OPR = ∠ORP

Now,

∠OPR + ∠ORP +∠POR = 180° (Sum of the angles in a triangle)

⇒ ∠OPR + ∠OPR + 160° = 180°

⇒ 2∠OPR = 180° - 160°

⇒ ∠OPR = 10°
