1. The problem statement, all variables and given/known data If cable AB is subjected to a tension of 700N determine the magnitude of the vertical force F in N.

The attempt at a solution I am retaking my statics course after i switched majors (long story) and i kind of forgot how to solve this the RIGHT way. My approach would be first breaking up all the tensions in the x y and z components and summing all of those. I'll end up with 3 equations and 3 unknowns (F, AC and AD). I just feel like that's too much work... On top of that my book makes use of i j and k but in those problems angles are given (which does make it easier to calculate the components) Could someone give me a quick rundown on how to solve this?
