Question

In the figure, PQRS and PTVS are two cyclic quadrilaterals, If ∠QRS = 100°, then ∠TVS =

पर्याय

• 80°

• 100°

• 70°

• 90°

Answer 1

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)
