Homework Statement
a block of mass (m) is placed on a bigger triangular shaped block with a mass (M). The wedge is of angle (α) . The coefficient of static friction between the two blocks is μs . What must the force (F) be in order to keep the smaller block at the same height on the wedge-shaped block? The answer is an equation in terms of the coefficient of friction, M, m, the angle and the gravitational acceleration. A FBD is also required. All laws must be documented and used properly.

The Attempt at a Solution
I have the answer, but I'm having trouble getting to it.
The answer to the problem:
F = (M+m)((sinα-μscosα/cosα-μssinα))g
