Trigo+Coordinate Geometry

Geometry Level 4

\[(\cos^{2}\theta \cos^{2} \alpha +\sin^{2}\theta)(x^{2}+y^{2})=(x\cot \alpha-y\sin\theta)^{2}\] The equation above represents a pair of straight lines. If the angle between the two lines is of the form: \( m\alpha+n\theta\), find the value of \( m+n+mn \).
