AB and CD are diameters. AC and DB are parallel.

Thus , d = 32 degree.

x = 32 degree . As d = x.

As two radius for isosceles triangle, hence angle d will also be 32, and both cords are parallel, so angle x must be equal to d hence answer is 32

$$OC = OA = OD = OB = Radius$$

$$∠OAC = ∠OCA = ∠ODB = ∠OBD = 32° = x°$$ (Vertically Opposite Angle)

Thus, Answer must be (D) 32°
