Question

In the given figure, O and O' are centres of two circles intersecting at B and C. ACD is a straight line, find x.

Answer 1

It is given that

Two circles having center O and O' and ∠AOB = 130°

And AC is diameter of circle having center O

We have

So

Now, reflex

So

$x°=360°-230°=130°$

Hence,
