Best ResponseYou've already chosen the best response.0There is a master equation to find the interior angle measure of any regular polygon. That equation is as follows: \[180^{o}(N2) = \theta\]where theta is your internal angle measure and N is the number of sides that the polygon has. To find the external angle measure corresponding to any internal angle measure, recall that for any polygon, the bounded internal and external angle measures sum up to 360 degrees. Therefore, to find an external angle measure, simply subtract the equation above's value from 360 degrees for a regular dodecahedron.

Best ResponseYou've already chosen the best response.0I'm sorry, I messed up a little. The equation above gives the TOTAL degrees contained by any polygon. You have to divide that number by N to get an individual internal angle measure. Then subtract that value from 360 to get an external angle measure.

Best ResponseYou've already chosen the best response.0thats strange im positive the interior angle is 150

Best ResponseYou've already chosen the best response.0well yea thats what i just did in the picture, and i'm sort of certain exterior angles have to be more than 180 so perhaps it means how much greater than 180 (which is a given) the angle is. In this case 30. what do you think?

Best ResponseYou've already chosen the best response.0Exterior angles always total 360 degrees regardless of the number of angles.
