Answer:
150
Explanation:
To find the measure of an interior angle of a regular dodecagon we use the formula : Sum = (n-2)180
There are 12 sides in this polygon. The "n" represents the number of sides in the polygon.
Sum = (n-2)180
= (12-2)180 = 10(180) = 1800.
But this the TOTAL amount of interior angles in this polygon. We only have to find 1. Like I said, there are 12 sides in this polygon and tofimdkne side we divide by 12.
1800 ÷ 12 = 150
