Question

in quadrilatetal ABCD angle A and angle C are complementary angle and angle B =124 then find D​

Answer 1

Answer:

<COD = 65°

As in the given figure ABCD is a quadrilateral circumscribing the circle and we know that, the opposite sides of a quadrilateral circumscribing a circle subtend supplementary angles at the center of the circle.

Therefore, <AOB + <COD = 180°

<COD = 180° - 115°

<AOB = 65°
