#### Answer:

#### Explanation:

To find the magnitude we use a similar idea as used to find the distance between two points.

Magnitude is:

For vector

( negative root not applicable)

So:

The direction is the angle formed between the vector and the x axis.

So we find the tangent ratio, which is:
