A block sits on an inclined plane, which is slowly being raised. The block remains motionless until the angle the plane makes with the horizontal is 23°. At this angle, the block begins to slide down the plane. What is the coefficient of static friction between the plane and the block?
F(static friction)= u(s) Fn
mgsin(23)= x component
mgcos (23)= y component

I don't know where to even start since it doesn't give me a mass or weight...
