Question

In the figure, PQRS is a cyclic quadrilateral. Find the value of x.
R​

Answer 1

Answer:

Answer:

Sum of either pair of opposite angles of a cyclic quadrilateral is 180°.

Sum of angles of ∆PRS = 180°

angle S + angle R + angle P =

180°

Angle S + 35° + 50° = 180°

Angle S = 180° - 85°

Angle S = 95°

Angle S + Angle Q = 180°

Angle Q = 180°- 95°

Angle Q = 85°
