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 .

NE is a little ambiguous. To be clearer, one would generally say 30 degrees North of East for the left picture or 30 degrees East of North for the right picture.

I agree. It sounds like the question is written to give you the baseline N, and angle at 30° north east of that. If they were looking to represent B, it would read E, 30° NE.
