Question

in the given figure ABCD is a cyclic quadrilateral with ab parallel CD if angle b is equal to 85 degree then find other angle of the quadrilateral​

Answer 1

Step-by-step explanation:

Sum of opposite angle of cyclic quard. is 180°

ABC + ADC = 180

=> 85 + ADC = 180

=> ADC = 95°

Since AB || CD

therefore

ABC + DCB = 180 k

=> 85 + DCB = 180

=> DCB = 95°

DCB + DAB = 180 [ sum of opposite angle of cyclic quard. ]

=> 95 + ABC = 180

=> DAB = 85°

A= 85

B = 85°

C = 95°

D = 95°

Answer 2

Answer:

A=85 B=85 C=95 D=95
