Two forces, (F1_vec) and (F2_vec), act at a point. (F1_vec) has a magnitude of 8.40N and is directed at an angle of 57.0 deg above the negative x axis in the second quadrant. (F2_vec) has a magnitude of 5.40N and is directed at an angle of 53.7 deg below the negative x axis in the third quadrant.
A) What is the x component of the resultant force?
B) What is the y component of the resultant force?
C) What is the magnitude of the resultant force?
