2003 AIME I Problem 11

An angle x is chosen at random from the interval 0^\circ < x < 90^\circ. Let p be the probability that the numbers \sin^2 x, \cos^2 x, and \sin x \cos x are not the lengths of the sides of a triangle. Given that p = d/n, where d is the number of degrees in \arctan m and m and n are positive integers with m + n < 1000, find m + n.

Leading zeroes must be inputted, so if your answer is 34, then input 034
