Question

In the given figure, ABCD is a cyclic quadrilateral ​

Answer 1

Answer:

68 DEGREE

Step-by-step explanation:

Since ABCD is a cyclic quadrilateral.

Therefore, sum of its opposite angles is 180 Degree.

Also, angle ADC + angle CDX = 180 degree (linear pair)

i.e. angle ADC + 68 = 180

From this equation, we get angle ADC as 112 degree.

Also, angle ADC + angle ABC = 180 degree (opposite angles of a cyclic quadrilateral)

Therefore, 112 + angle ABC = 180

From this equation we get angle ABC as 68 degree
