It has (8820+360)/180 = 51 sides
How many sides does a regular polygon have if each exterior angle measures 20?
53 sides Interior angels always add up to (number of sides -2)*180 so reverse the process: 9180/180=number of sides -2. 51=sides -2. Sides = 53
A 51-sided polygon is called a pentacontahenagon.
The name of a 51 sided polygon is Pentaconhenagon. The name of a 52 sided polygon is Pentacondigon. The name of a 53 sided polygon is Pentacontrigon.

How many sides does a regular polygon have if each exterior angle measures 20?
It has 51 sides, and it doesn't have to be regular.
(n - 2)x180 where n = number of sides so ... 51 x 180
53 sides Interior angels always add up to (number of sides -2)*180 so reverse the process: 9180/180=number of sides -2. 51=sides -2. Sides = 53
A 51-sided polygon is called a pentacontahenagon.
0.5*(172-51) = 119 diagonals
Altogether there are: (5*5)+(3*6)+(1*8) = 51 sides
