1.	If PQ and PR are two tangents to a circle with centre O.If ∠QPR = 46°, find ∠QOR.
Answer» ∠QOR + ∠QPR = 180° (Supplementary angles) ⇒ ∠QOR + 46° = 180° ⇒ ∠QOR = 180° – 46° = 134°. angQOR = 360^o -2×90^o -46^o =134^o

If PQ and PR are two tangents to a circle with centre O.If ∠QPR = 46°, find ∠QOR.

Answer»

∠QOR + ∠QPR = 180° (Supplementary angles)

⇒ ∠QOR + 46° = 180°

⇒ ∠QOR = 180° – 46° = 134°.

angQOR = 360^o -2×90^o -46^o =134^o
