Question

2)
squarePQRS is a cyclic quadrilateral.
angleP=85° then find angleR.​

Answer 1

Answer:

p+r=180°(opposite angles of cyclic quadrilateral is 180)

85+r=180

r=180-85=105

Answer 2

Answer:

Step-by-step explanation:

Since PQRS is a cyclic quadrilateral

So it's opposite angles are supplementary i. e sum of 180 degree

Angle P ➕ Angle R =180 degree

85+R=180

R=180-85

R=95
