Question

9. consider the vector V=(-6,13)

part1: use the dot product to find the angle (in degrees) between V=(-6,13) and the vector (1,0)

part2: write V in the form (|V|cos theta|V|sin theta) express the angle theta in degrees

part3; use the dot product of the vectors V=(-6,13) and W=(-42,-34) to determine if they are orthogonal
