Expression in Terms of Theta

A crate weighing $w$ pounds sits on a ramp positioned at an angle of $\theta$ with the horizontal. The forces acting on this crate are modeled by the equation $Mw cos \theta = w sin \theta$ , where $M$ is the coefficient of friction. What is an expression for $M$ in terms of $\theta$ ?

a) $M = tan \theta$

b) $M = sec \theta$

c) $M = cot \theta$

d) $M = csc \theta$
