As shown in the figure, three force vectors act on an object: The magnitudes of the forces are F1 = 80.0 N, F2 = 60.0 N, and F3 = 40.0 N, where N is the standard SI unit of force. The resultant force acting on the object is given by:
A) 35.5 N at an angle of 34.3° with respect to the +x-axis.
B) 180 N at an angle of 60.0° with respect to the +x-axis.
C) 60.0 N at an angle of 90.0° with respect to the +x-axis.
D) 40.0 N at an angle of 60.0° with respect to the +x-axis.
E) 20.0 N at an angle of 34.3° with respect to the +x-axis.
