Explanation / Answer

Resolve into x, y and z components: (F_3:: x: - F_3cosphisin heta;;; y: F_3cosphicos heta;;; z: -F_3sinphi) (F_1:: x: - F_1cosphisin heta;;; y: F_3cosphicos heta;;; z: -F_1sin 60^circ) (F_2:: x: 8(3/5);;; y: 0;;; z: -8(4/5)) Now add these as vectors and find the magnitude: (sqrt{x^2 + y^2 + z^2}) and the angles are easy - by trigonometry!
