Analyze the provided image and describe the geometric shapes and any labeled angles or variables.

The image displays a circle with center O. Points A, B, C, and D are on the circumference of the circle. AC appears to be a diameter passing through the center O. Angles are labeled as follows:

• An angle is labeled as 35°, with its vertex at point B and subtended by arc AD. The angle appears to be ∠ABD or a similar angle involving these points.
• An angle is labeled as x, with its vertex at point A and subtended by arc BD. This angle appears to be ∠BAD.

The shape ABCD is a cyclic quadrilateral. AC is a straight line and passes through the center O, indicating it is a diameter.
