Vector has a magnitude of 63 units and points due west, while vector B has the sasme magnitude and points due south. Find the magnitude and direction of a) A + B and b) A - B. Specify the directions relative to due west.
Can someone include a drawing to help me understand how the vectors look when added and subtracted so I can understand the steps?
