Find the measures of the interior angles of the regular polygon

You need to identify that number of sides of the polygon. In this case it has 12 sides.
In order to find the measure of the interior angles of a polygon, you can use the formula shown below:
[tex]InteriorAngle=\frac{180(n-2)}{n}[/tex]Where "n" is the number of sides of the polygon.
In this case you know that:
[tex]n=12[/tex]Finally, substituting the value of "n" into the formula and evaluating, you get the following result:
[tex]\begin{gathered} InteriorAngle=\frac{180(12-2)}{12} \\ \\ InteriorAngle=\frac{1800}{12} \\ \\ InteriorAngle=150\degree \end{gathered}[/tex]Since it is regular, all the interior angles have equal measure.
Therefore, the answer is:
[tex]150\degree[/tex]
