Given the tower is 70 m high, and the force of FAB= 2 kN and the x and z components of the vector sum of the forces exerted on the tower by the 3 cables are zero. I have found the lengths of all 3 cables. I have also found the unit vectors for all 3 cables. I just do not know how to find the magnitude of FAC and FAD. I have attached a screen shot of the drawing and my work.
