Question

The measure of the arc from B to A not passing through C is 30 degrees. Find the measure of each of the angles below

Answer 1

BOA-30(Given)

BCA-15(See explanation)

BDA- 15(NOT SURE)

Explanation:

*Angle at the center is twice the angle at the circumference.

If angle at the center(30) is twice BCA, then BCA is 15.

*I think BDA deals with alternate angles, so might be 15.
