Vector addition with 4 force vectors

    1. The problem statement, all variables and given/known data

    2. Relevant equations



    3. The attempt at a solution

    I'm not sure at all how to do this to get the resultant vector, other than using the head-to-tail method by scaled vectors, which I really don't want to do and work out because it seems like it'd be too time consuming if I was to encounter a problem like this on a test..

    I'm not too sure about this at all, so if anyone can give me a hint or something on how to start, it'd be appreciated. Thanks

    If you break up each vector into its x and y components, then add the x components, and then separately add the y components, you end up with 2 force vectors at right angles to each other, one in the x direction and the other in the y direction. Now find the resultant of those 2 vectors. Please watch plus and minus signs.
