Square root of (5cos(theta)+12sin)theta)squared+(12cos(theta)-5sin(theta))squared=13
---------------


sqrt%28%2850cos%5E2%28t%29+%2B+288sin%5E2%28t%29%29%29+=+13
%28%2850cos%5E2%28t%29+%2B+288sin%5E2%28t%29%29%29+=+169
%28%28238sin%5E2%28t%29%29%29+=+119
%28%28sin%5E2%28t%29%29%29+=+0.5
sin(theta) = sqrt(2)/2
theta = 45º
