Question

In a cyclic quadrilateral A B C D. A B is parallel to C D and angle B is 70 degree. Find remaining angles.

Answer 1

angle B + angle D =  180 {opposite angle of cyclic quadrilateral}

angle D = 110

again  angle B + angle C = 180  [co interior angle]

angle C = 110

again     angle C + angle A = 180 {opposite angle of cyclic quadrilateral}

angle A = 70

Answer 2
