← A port's radar takes east as the x axis and north as the y axis. A ship's position from the port is (-5î + 12ĵ) km. How far is the ship from the port, and in which direction?Two vectors A and B are drawn from the same point. A student finds that |A + B| = |A - B|: the two diagonals of the parallelogram they make are equally long. The angle between A and B is →
