Question

in the given figure ABCD is a circlic quadrilateral if angle b a d is equal to 105 degree and angle c b equal to 65 degree then find the value of x​

Answer 1

Answer:

Step-by-step explanation:

For segment DABCD

< DAC &DBC are in same segment ,

So they will be equal

Therefore < DAC =<DBC =55°

Now ,

<BAD = <DAC+<BAC

=55°+45°=100°

Now in cyclic quadrilateral ABCD

<BAD + <BCD =180°

100° +<BCD =180°

<BCD =180°-100°

<BCD =80°
