I need to determine the magnitude of resultant force R

And, determine the coordinate direction angles α,β, γ of force R

I just can't seem to understand 3-d vectors. I'm fine with 2-d, but this is so different to me. The answers are given in bold I just don't know how to get there. I'd really appreciate any help/explanations. I've asked multiple people for help and they were all confused.

I would ask my professor, but he has a very strong accent and is difficult to understand.

Thanks so much!
