Answer: To find for the magnitude and direction of a resultant force when doing vector addition is to find first for the x and y components of the vectors to be added. ... 
-x-axis. ... 
F1 = 5.6 newtons eastward; F2 = 12 newtons 30 degrees west of north; F3 = 9.4 newtons 60 degrees south of west.
F1 is eastward hence it is 0 degrees.
