Vector A has a magnitude of 9.60 units and makes an angle of 49.0° counter-clockwise from the positive x-axis. Vector B has a magnitude of 8.00 units and is directed along the negative x-axis.

(a) Using graphical methods, find the vector sum A + B.

*Magnitude of A + B: units

*Direction of A + B: ° counterclockwise from +x-axis

(b) Using graphical methods, find the vector difference A - B.

*Magnitude of A - B: units

*Direction of A - B: ° counterclockwise from +x-axis

What you need to do is get the arc tan of vector b/vector a(arc tan of three/6 or 0.5) this gives you you the degress relative from the x axis... purely undergo in recommendations that for area (a) you have a damaging fee and for area b) you have a good.
