(b) 50
(c) 60
(d)75​

Answer 1

Step-by-step explanation:

In the figure,

OA = OC = OD = OB ( all are radius of circle of center o)

Now,

angle CAO = angle OBD = 50° ( alternate angles)

Now,

In triangle OBD

angle OBD = 50°

OD = OB ( radii of same circle )

Therefore,

angle ODB = 50°

because opposite angle of equal sides are equal
