Question

Answer 1

Answer:

In cyclic quadrilateral Opp. angle x+x=180 degree always so value of angle A = 180-104=76

So, as you can see that a chord is passing through center o

So, that is equal to 180 degree

So, angle a+ angle b=90 degree

So, 90-76=14 so,

Angle a=76 degree. And angle B=14 degree.

I hope that it is helpful to you.
