    now add the components to find the resultant of the system and use it to find the magnitude and direction angle. ----------------------> can anyone please explain it to me how to add the components by using those numbers above? and how can I use those number to find the magnitude and direction angle? Thank you for answering my question!

    If those are vectors and you are asking for the magnitude and direction of each, apply the dot product formula for finding angles.
