Select the correct answer from each drop-down menu. Diagram shows horizontal line segment AB with point P lies on it. Segment NP makes a right angle with segment AP. Segment DP makes an acute angle y with segment BP. Segment CP makes an acute angle x with segment BP. In the diagram, P ⁢ N ― is the perpendicular bisector of A ⁢ B ― and the angle bisector of ∠CPD. sin ∠BPD = , and cos ∠CPN = .
