Remember the equation.
Exterior Angle = 360/n (No. of sides)
Hence
Ext. Ang. = 360 / 18
Ext. Ang. = 20 degrees.
Hence the corresponding Interior Angle will = 180 - Exterior Angle.
Int. Ang. = 180 - 20 = 160 degrees.

What will be the measure of an exterior angle of a regular 18 sided polygon?
56
What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
Each exterior angle of a regular polygon measures 20 degrees how many sides does the polygon have?
The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
What are the exterior angles on a 20 sided polygon?
The sum of the exterior angles of any polygon and the extension of its adjacent side is 360 degrees.If the 20 sided polygon is regular, then each angle is equal so that each one is 360/20 = 18 degrees.
What are the interior and exterior angles of a regular 18 sided polygon?
The measure of an interior angle in degrees of a regular polygon of n sides is given by the formula: 180 x (n-2) / nSubstituting with n=18, then the answer is that the interior angle = 160The measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/nSubstituting with n= 18, then the answer is that the exterior angle = 20

What is the exterior angle of an 18 sided shape?
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?
What is the measure of each exterior angle of an 18 sided polygon?
20 degrees
What is the measure of each exterior angle of regular 18 sided polygon?
20
What is the measure of an exterior angle of a regular 18-sided polygon to the nearest tenth?
Each exterior angle will measure 360/18 = 20.0 degrees
What is the measure of an exterior angle of a regular 20- sided polygon?
360/20 = 18 degrees.
What is the measure of each exterior angle of a regular 18- sided polygon?
20
What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
What is the sum of the external angle measures of a 18-sided polygon?
The exterior angles of any polygon add up to 360 degrees
Each exterior angle of a regular polygon measures 20 degrees how many sides does the polygon have?
The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
What are the exterior angles on a 20 sided polygon?
The sum of the exterior angles of any polygon and the extension of its adjacent side is 360 degrees.If the 20 sided polygon is regular, then each angle is equal so that each one is 360/20 = 18 degrees.
