Question

In the figure, angle ABC = 40° then find angle ADC
​

Answer 1

Answer:

140

Step-by-step explanation:

We can observe that ABCD is a cyclic quadrilateral

And by the property of Cyclic quadrilaterals,

The sum of opposite sides = 180

Hence, ABC + ADC = 180

40 + ADC = 180

ADC = 140

Answer 2

Answer:

140

Step-by-step explanation:

ABCD is a cyclic quadilateral

And by the property of cylic quadilateral

The sum of opposite side= 180

ABC+ADC= 180

40+ADC= 180

ADC= 180-40

ADC= 140
