1. The problem statement, all variables and given/known data
I need help with this hw problem. 1st vector: 80 N & 180 degree 2nd vector: 40 N & 145 degree 3rd vector: 50 N & 50 degree And I need to find the resultant and the Eq. Where do I start and how do I do it please include answer as I'm confuse and I have a quiz on this soon. thanks 2. Relevant equations 3. The attempt at a solution

Hi needhelp 1, welcome to PF.
Do you know how to find the components of a vector along x and y axis? If you know find the components and find ΣFx and ΣFy. Then find the resultant.
