Help with Vector/magnitude Vector A has a magnitude of 7.30 units and makes an angle of 46.5° 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 I am having trouble with that problem and I was wondering if I drew my graph correctly?
