angle? Show your work

Question

surjithayer · Answer

sum of interior angles of a nonagon=(9-2)*180=7*180=1260 degrees
so there is something wrong in your statement.

surjithayer · Answer

sum of exterior angles of a regular polygon=360
each exterior angle=360/9=40 degree
so each interior angles of a regular nonagon=180-40=140 degrees.
