Question 552625: A dodecagon is a polygon with 12 sides. How many degrees is each of the interior angles in a regular dodecagon? Show or explain how you got your answer.
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
I = (180(n-2))/n
I = (180(12-2))/(12)
I = (180(10))/(12)
I = 1800/(12)
I = 150
So the measure of each interior angle of a 12-sided polygon is 150 degrees.
