The cable AO exerts a force on the top of the pole of F = {—120i — 90j — 80k} lb. If the cable has a length of 34 ft, determine the height z of the pole and the location (x,y) of its base.
[A]. x = 16 ft, y = 16 ft, z = 25 ft
[B]. x = 12 ft, y = 9 ft, z = 8 ft
[C]. x = 20 ft, y = 10 ft, z = 14 ft
[D]. x = 24 ft, y = 18 ft, z = 16 ft
