Two people are pulling a mule. One is pulling at 120 N* at 60 degrees, and the other is pulling at 80 N* at 105 degrees. Find:

a) The single force that is equivalent to the forces shown.

AND

b) The force that a third person would have to exert on the mule to make the resultant force equal to zero.

*N for units of newtons.

    Break each vector into two components. Not having a diagram, I cant help. But I suspect one component should be aimed along whereever the angles are being measured from, and the other angle perpendicular to that.
    Then add like components.
