I need answer for B (the magnitude)

The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take F, = 130 N and F, = 63.0 N.) F2 F1 75.00 60.0 X (a) Find the single force that is equivalent to the two forces shown. magnitude 180.14 N direction 74.32 . counterclockwise from the +x-axis (b) Find the force a third person would have to exert on the mule to make the net force equal to zero. magnitude IX Your response differs from the correct answer by more than 10%. Double check your calculations. N direction 257 . counterclockwise from the +x-axis L O
