Problem

In the figure below, AC and BD are diameters of circle P.
What is the arc measure of major arc BDC in degrees?
A circle that is centered around point P. Points A, B, C, and D all lie on this circle in a clockwise direction. Line segment A C and line segment B D are diameters of the circle. Line segments A P, B P, C P, and D P are radii of the circle. The angle A P D is a one hundred fifty-five degree angle.
