We have to find angle BPD, which is the angle formed by a tangent and a secant. The intercepted arcs are minor arcs.
Therefore, angle BPD = (1/2)[measure of arc BD - measure of arc AD] = (1/2)[105º - 55º] = [spoiler]25º[/spoiler]
The correct answer is E.

Your attachment is not representing the question exactly. You should have treated the minor arc as the intercepted arc. [spoiler]B is not correct[/spoiler].neelgandham wrote:From the attachment, [spoiler](B)100°[/spoiler]
