Im sure I got (a), but I have no idea what it is asking for in (b). (a) Find the single force that is equivalent to the 2 forces shown. (b) What is the value of a third force to make the net force zero.

    \[(a)=80sin(75^o)+60\sqrt{3}=181.2~N\]

    \[-80cos(75^o)+120cos(60^o)=39.3N\] so maybe its asking to find a third value that will balance that part of it out
