Question

ABCD is a cyclic quadrilateral if AB || DC and angle b = 70 degree find the other angles of ABCD​

Answer 1

since ab||dc

the sum of opposite angles in cyclic quadrilateral are supplementary ie.180

angle abc=dcb =70 ab||dc

angle abc+adc=180

adc=180-70=110=bad

bad=adc=110

abc=dcb=70

Answer 2

Step-by-step explanation:

       since ab||dc

the sum of opposite angles in cyclic quadrilateral are supplementary ie.180

angle abc=dcb =70 ab||dc

angle abc+adc=180

adc=180-70=110=bad

bad=adc=110

abc=dcb=70
