Intersecting Lines and Angle Measures

In a geometric diagram, two lines intersect at point P, forming four angles. The measures of two of the angles are given as follows:

Angle 1 (∠APB) measures 70 degrees, and angle 2 (∠BPC) measures 110 degrees. Based on the properties of angles formed by intersecting lines, determine the measure of angle 3 (∠BPD).
