Rank the vector combinations on the basis of their magnitude.
A+C, A+B, A+D, A+E, F+C, D

A+C> A+B =A+D > D =F+C >A+E

Rank the vector combinations on the basis of their angle, measured counterclockwise from the positive x axis. Vectors parallel to the positive x axis have an angle of 0? . All angle measures fall between 0? and 360?
A+C, A+B, A+D, A+E, F+C, D

A+B>F+C=D>A+D>A+E=A+C
