Problem: Two forces, F1 and F2, act at a point, as shown in the picture. (Fiqure 1) F1 has a magnitude of 8.80 N and is directed at an angle of α-65.0° above the negative x axis in the second quadrant. F2 has a magnitude of 5.40 N and is directed at an angle of β = 53.3° below the negative x axis in the third quadrant. A) What is the x component Fx of the resultant force?B) What is the y component Fy of the resultant force?C) What is the magnitude F of the resultant force?D) What is the angle ? that the resultant force forms with the negative x axis? In this problem, assume that positive angles are measured clockwise from the negative x axis.
