Question

In a cyclic quardrilateral two adjecent angles are 40° and π÷3 radian find the angles of the quardrilateral in degree

Answer 1

Step-by-step explanation:

In a cyclic quad. , sum of opposite angle is 180° .

If ABCD is the quad. and angle A =40°

and angle B = π÷3 radian

= 180÷3 °

= 60°

So, angle C = 180 - angle A

= 140°

and angle D = 180 - angle B

= 120°
