for which one

The exterior angles of a polygon always add up to 360 degrees. If you have a regular octagon, it will have 8 sides (and obviously 8 exterior angles). 360 / 8 = 45° degrees.

7. yrelhan4

Each exterior angle of a regular12-sided polygon measures 360/12=30 degrees Therefore each interior angle measures 180-30=150 degrees

8. yrelhan4

sum of an interior angle of a regular polygon = 180º(n – 2) for 20-gon = 180 * (20 -2) = 3240º

done?

What is the value of x in the regular polygon below? A Regular Polygon is a polygon with all sides and all angles equal. so 360/6=30degrees each angle. so x=10 degrees.
