14. In △ABC, AB=10, ∠A=30∘, and ∠C=45∘. Let H, D, and M be points on the line BC such that AH⊥BC, $∠BAD=∠CAD$ (Error compiling LaTeX. ! Package inputenc Error: Unicode char \u8:∠ not set up for use with LaTeX.), and . Point is the midpoint of the segment , and point is on ray such that PN⊥BC. Then , where and are relatively prime positive integers. Find .
