Step 1
Calculate the size of the interior angle of a regular polygon.
Answer
To find the size of the interior angle of a regular polygon, we use the formula:
ext{Interior Angle} = rac{(n - 2) imes 180}{n}
where is the number of sides. For a 12-sided polygon, we have:
ext{Interior Angle} = rac{(12 - 2) imes 180}{12} = rac{10 imes 180}{12} = 150
Thus, the interior angle of a regular 12-sided polygon is degrees.
