Let A(Vector) represent any nonzero vector. Why is A(Vector)/A a unit vector, and what is its direction?

Question:

Let A̅(Vector) represent any nonzero vector. Why is A̅(Vector)/A a unit vector, and what is its direction? If θ is the angle that A̅(Vector) makes with the +x-axis, explain why (A̅(Vector) /A) ∙ î is called the direction cosine for that axis.
