Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape

Each interior angle measures 160 degrees

Providing that it's a regular polygon each interior angle is: 1520 18' 27.69''

It wil be a regular 18 sided polgon

Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o

To work out the interior angle use this formula(n - 2)*180/nwhere n is the number of sidesso for an 18 sided shape it would be(18-2)*180/18 = 160.

The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.

Each interior angle measures 160 degrees

Providing that it is a regular 18 sided polygon each interior angle measures 160 degrees.

Providing that it is a regular polygon then each interior angle will measure 160 degrees

The exterior angle of a 18 sided shape is 360/18 =20 degrees The exterior angle is always 360 divided by the numbe of sides of that polygon. =) what the hell im i doing answering this?

exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°

2880 degrees
