Question

Four forces act on an object, given by 

A = 40.3 N east, 
B = 43.3 N north,
C = 74.7 N west,
D = 78.7 N south.

 (Assume east and north are directed along the +x-axis and +y-axis,respectively.)

(a)
What is the magnitude of the net force (in N) on the object?
 
(b)
What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)
