But then I did say that I'm NOT a physicist or mechanical engineer. Guess I won't be quitting my day job anytime soon

sine of 40 degrees, cosine of 40 degrees and so forth from trigonometry. And they came from the diagram (total force F being the hypotenuse of a right triangle, its "base" vertical component of the force (COS(40)), the other, the normal component (pushing towards the wall) causing the frictional force (SIN(40)).
