Hi

If a man is pushing a box up a hill using a horizontal force, why is the angle in the diagram equal to theta? Is it because the angles are alternate angles of a pair of parallel lines (Fpush and the ground are parallel)

thanks

Yes, because you break Fp into the X and Y dimensions in relation to hill, you create like angles where the hill meets 0 (the ground) and Fp meets the hill at X,Y. Thus you have Fpy, Fpx, and Fp creating a right triangle
