$(5$ points$)$ Textbook, Ch $1,$ Problem $86$

Two vectors vec$(A)$ and vec$(B)$ have magnitude $|vec(A)|=3\mathrm{.}00$ and $|vec(B)|=3\mathrm{.}00.$ Their vector product is vec$(A)$vec$(B)=-5\mathrm{.}00$hat$(k)+2\mathrm{.}00$hat$().$ What is the angle between vec$(A)$ and vec$(B)?$ Express your answer in degrees.
