1) the sum of forces in any direction is zero.

2) THe sum of moments about any point is zero.

So, draw the figure. Sum forces in horizontal, and vertical equations: that gives you two equations.

Sum moments about any point on the ladder, I suggest the base.

With these three equations, you have it.
