Homework Statement
The z component of the force F is 80 lb. (a) Express F in terms of components. (b) what
are the angles x, y, and z between F and the positive
coordinate axes?
Homework Equations
The equations that I attempted to use were directional cosines, trignometric identities and that F = (magF)(cosθ)
The Attempt at a Solution
I haven't really been able to get anywhere. I tried various methods:
1) I tried to find the length of A and use that to find F and so forth.
I have been at this for a good hour and the answer is most likely something simple.
