There are two major resonance structures for $"NO"_2$ .

You must first draw the Lewis structure for $"NO"_2$ .

You find that you can draw two Lewis structures.

The $"N"$ atom has an unpaired electron and a positive charge.

Every atom has a formal charge of zero.

These are the two major resonance contributors to $"NO"_2$ .
