because
if exterior = 20 degrees, then the interior must equal 160 degrees...
using the formula:
(n-2)x180=160n...
(n-2)180=160n
180n-360=160n
180n-160n-360
20n=360
n=18

If it's regular polgon then: 360/32 = 11.25 degrees The exterior angles of any polygon add up to 360 degrees
180
160 degrees. The sum of all interior angles in a N-sided polygon = (N-2)*180°If the polygon is regular, then divide by N, so each angle is (1-2/N)*180°Additional Information:-The exterior angles of any polgon add up to 360 degrees. So if it is a regular polygon simply divide the number of sides into 360 which will give each exterior angle and to find its interior angle is: 180 - exterior angle.In this case: 360/18 = 20 degrees exterior angle.180 -20 = 160 degrees interior angle.
An hexagon is a 6 sided polygon that can be regular or irregular

If it's regular polgon then: 360/32 = 11.25 degrees The exterior angles of any polygon add up to 360 degrees
If its a regular polgon and each exterior angle is 30 degrees then it will have 360/30 = 12 sides
180
The sum of the exterior angles of a polgon - no matter how many sides - is 360 degrees.
Presumably you mean each interior angle measures 175 degrees if so then it will have 72 sides because angles on a straight line add up to 180 degees 180-175 = 5 degrees (the exterior angle) The exterior angles of the polgon add up to 360 degrees 360/5 = 72 sides
160 degrees. The sum of all interior angles in a N-sided polygon = (N-2)*180°If the polygon is regular, then divide by N, so each angle is (1-2/N)*180°Additional Information:-The exterior angles of any polgon add up to 360 degrees. So if it is a regular polygon simply divide the number of sides into 360 which will give each exterior angle and to find its interior angle is: 180 - exterior angle.In this case: 360/18 = 20 degrees exterior angle.180 -20 = 160 degrees interior angle.
An hexagon is a 6 sided polygon that can be regular or irregular
720 degrees
The name of a regular polygon with five equal sides and five equal angles is a pentagon. Each of the internal angles is equal to 108 degrees.
It can be, if its sides all have the same length.In that case, it would also be called a 'square'.
It wil be a regular 18 sided polgon
