Find the magnitude and direction angle (to the nearest tenth) for each vector. Give the measure of the direction angle as an angle in [0,360°].
(-12,5)
----
Note: That point is in QII
-------
magnitude = sqrt[12^2+5^2] = 13
------
direction = arctan(5/-12) = -22.62 or 180-22.62 = 157.38 degrees in QII
