Question
In the figure, PQRS and PTVS are two cyclic quadrilaterals, If ∠QRS = 100°, then ∠TVS =
Options
80°
100°
70°
90°
Solution
100°
Explanation;
Hint:
∠SPQ = 180° – 100° ...(Opposite angles of a cyclic quadrilateral PQRS)
= 80°
In the cyclic quadrilateral PVTS,
∠V = 180° – 80° = 100° ...(Opposite angles of a cyclic quadrilateral)
