How do you calculate the net force when there are multiple forces in different directions?

To find we need to use vector addition and use the x and y components. First we subtract vector 2 from vector 5 which results in a vector with a  length of 3 pointing directly east, then we use the distance formula to find the length of the net force  which gives . We now have a magnitude but we also need a direction, since vector 4 and vector 5 are perpendicular. Using   where tan^-1(y/x) we get an angle of 53 degrees. The resultant force vector is 5 distance with an angle of 53 degrees north east.

this is a good question! i'll do some research and come back when i have the answer!
