Find the angle feta between the vectors.
HOW TO:
find the angle - cos(feta)=U*V/magnitudeU*magV
find mag - sqrt U squared plus V squared
13. u=(-4,-30), v=(-1,5)
14. u=(2,-2), v=(-3,-3)
15. u=(2,3), v=(-3,5)
16. u=(5,2), v=(-6,-1)
17. u=3i-3j, v= -2i+2sqrt3j
21. u=(-3,4), v=(8,5)
22.u=(-3,8), v=(-1.-9)
