∙ 14y agoInterior angle = 140 degrees so exterior angle = 180 - 140 = 40 degrees.
Sum of exterior angles = 360 degrees so number of angles = 360/40 = 9 sides.

∙ 14y agoThe interior angle of any regular polygon can be calculated using the formula 180 * (n - 2) / n, where n is the number of sides. In this case, since each exterior angle measures 72 degrees, the interior angle would be 180 - 72 = 108 degrees. So the measures of the interior angles in this regular polygon would be 108 degrees.
If it's a regular polygon then each interior angle measures 120 degrees.

A regular 12 sided polygon each interior angle measures 150 degrees
If each interior angle measures 174 degrees then it will have 60 sides
Not possible - the smallest interior angle for a regular polygon is 60 degrees - which creates an equilateral triangle.
540 degrees
Providing that it is a regular 18 sided polygon each interior angle measures 160 degrees.
The polygon will have 12 equal sides and each interior angle measures 150 degrees.
