Answer:
50⁰
Step-by-step explanation:
Given angle subtended by AC at centre is 100⁰.
Thus, Angle subtended at any other point on the same segment where centre lies will be 50⁰.
So let any other point on the circle be P.
Thus, angle APC = 50⁰.
Using Alternate Segment Theorem, we get Angle CBD would be angle APC=50⁰.
