find the angle between the given vectors to the nearest tenth of a degree.
u=sq.root5i-8j, v=sq.root5i+j
--------------------
standard angle with terminal side
thru (sqrt(5),-8) is arctan(-8/sqrt(5)) = 285.62 degrees
-----
standard angle with terminal side
thru (sqrt(5,1) is arctan(1/sqrt(5) = 65.91 degrees
----
Angle between = 285.62-65.91 = 219.71 degrees
