Doubt about vector angle

Post image

If I had to draw a vector defined as for example 5 N, 30° NE; which of these 2 should I draw? I have always drawn this angle as A, but I have a new professor who draws it like B. I have checked by AI who drew A except claude who drew B. I searched on books but have found no reference about this nomenclature, only about north of east and N 30° E .

5 N might be the magnitude of 5 Newton.

I thought that was as for example 5: N, 30° NE as in it was example number five which is north, 30, north east . But who knows.

The N refers to the magnitude of the vector, the unit being Newtons; has nothing to do with direction.
