Exteriors angles of the regular nanogon?

Answer 1

Never heard of a 'nanogon'. If you mean 'Nonagon'. note the spelling.

The the exteriod angle is

EXT Ang = 360 / 9 = 40 DEGREES.

Remember for any REGULAR polygon the EXTETRIOR Angle is '360' divided by the given number of sides (n).

Algebriacally.

Ext. Ang = 360 / n

Answer 2

For regular polygons all the exterior angles are the same, and like all polygons they add to 360°. So each exterior angle is 360 divided by the n, the number of sides. Hope this helps.
