Question 819145
Find the angle θ between the vectors. (Round your answer to two decimal places.) 
u = 8, 5 
v = 9, 0 
theta = ____ degree
--------------------------
(9,0) is on the positive x-axis
--------------
The angle made by the positive x-axis and 
a line thru (8,5) is arctan(5/8) = 32 degrees
-------------------------
