cos Θ = A/H = x/F

Well, for the u and v, you do the same thing. You consider a right triangle, where the hypotenuse is F, the adjacent side is the u component, and the other side is a component perpendicular to u (not v). Θ is the angle between the force vector and u, in this case 21, and you can solve for u

cos Θ = A/H = u/F

Solving for v is a similar problem
