1. forces in opposite directions subtract from each other

so the "effective forces here are ... 6N north and 2N east

magnitude ... √(6^2 + 2^2)

direction ... [arctan(2 / 6)] east of north

2. Force total=8N + 6E + 2S +4W= N (8-2) + E(6-4)= you finish
magnitude = sqrt (6^2+2^2)
direction= arctan E/N=arctan 2/6 E of N
