A regular pentagon is inscribed in a circle of radius 5 units . P is any point inside the pentagon. Perpendiculars are dropped from P to the sides, or the sides produced, of the pentagon.

The sum of the lengths of these perpendiculars can be expressed in the form mn+op \frac{ m\sqrt{n} + o}{p} , where these are all positive integers such that oo and pp are coprime, and nn is not divisible by the square of any prime.

Find the sum :m+n+o+p m+n+o+p .
