Four forces act on an object, given by
A = 47.3 N east,
B = 36.3 N north,
C = 86.7 N west,
and
D = 72.7 N south.
(Assume east and north are directed along the +x-axis and +y-axis, respectively.)

I don't mind helping to find answers, but I resent having to provide the questions as well.
What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)
thats the question sorry
F = A+B+C+D = (47.3-86.7) i + (36.3-72.7) j = -39.4i -36.4j
the direction is θ where tanθ = -36.4/-39.4
θ = 222.73°
the direction is θ where tanθ = -36.4/-39.4
θ = 222.73°
