# Are angles for vectors always measured from the horizontal?

I have a vector which has been stated to have a force of: 96.0 N at $51.3^\circ$. I had a different answer because I was measuring my angles from the north. By default if an angle is given by itself are we to assume that it is being measured from the horizontal axis?

For example I expected to see: 96.0 N at $51.3^\circ$ (from east/horizontal).
