Interior Angles of a Pentagon

Very Easy Geometry Polygons

Consider a regular pentagon, which is a polygon with five equal sides and angles. If each interior angle of the pentagon is represented as $$x$$, what is the value of $$x$$?

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

$$x =\frac{(n-2) imes 180}{n}$$

where $$n$$ is the number of sides in the polygon.

In this case, for a pentagon, what is the value of $$x$$?
