Step-by-step explanation:

Right ha 100%

Answer 2

Answer:

The answer will be 50degree

Construct a tangent which intersect point A and name it XY.

Therefore angle OAY = 90 degree

Now, angle OAB = OAY - BAY

OAB = 90 - 40

OAB = 50degree.

Here triangle ABC is an isosceles triangle

So, angle OAB = angle OCB

There x = 50degree.

Hope this will help.
