I have racked my brain for the past two hours and I can't figure this out. If any one can help me with, please do.(adsbygoogle = window.adsbygoogle || []).push({});

Two long parallel wires 6.00 cm apart carry 19.5 A currents in the same direction. Determine the magnetic field strength at a point 12.0 cm from one wire and 13.4 cm from the other. (Hint: Make a drawing in a plane containing the field lines, and recall the rules for vector addition.)

I found the magnetic field for each of the wires seperately using B = Mo(I)/ r

but I cannot understand what the "vectors" have to do with the problem.
