# Finding distances/similarity between vectors

Let's say for example I have these three vectors representing these three fields:

$$\begin{array}{c|c|c} \text{Cars Sold} & \text{Cars in Lot} & \text{Profit Generated}\\ \hline \\140 & 89 & 987781 \\ 23 & 210 & 789000 \\ 300 & 12 & 1900000 \end{array}$$

I want to find which vector is the most similar to this: $[189, 45, 1300000]$

Since these vectors have fields that aren't all of the same magnitude, would it be appropriate to use euclidian distance between these vectors to find which has the shortest distance?

Also, could cosine similarity be used as well?
