The Attempt at a Solution

I don't know where to begin... My attempt isn't even worth putting up..

How would you solve this if it were in 2 dimensions?

 

[erainer]

By using the distance formula? I tried doing that but I must be doing it wrong.

 

[I like Serena]

Start by finding the x, y, and z components of each force and adding them?

Can you find the direction of each force (x,y,z) to start with?
