Consider a regular pentagon (a five-sided polygon) inscribed in a circle. Each side of the pentagon is equal in length, and each interior angle is equal in measure. What is the measure (in degrees) of each interior angle of the regular pentagon?

To find the measure of an interior angle of a regular polygon, you can use the formula:

$$ ext{Interior angle} = rac{(n-2) imes 180}{n}$$

where $n$ is the number of sides.
