Answer 1

Use the formula

\[\Large \theta = \frac{u \cdot v}{|u||v|}\]

Answer 2

|u| is the magnitude or length of vector u

|v| is the magnitude or length of vector v

Answer 3

but when i did this i got an answer that wasnt even one of the answer choices

Answer 4

what did you get

Answer 5

first tell me what the magnitudes of each vector are
