To find the measure of the central angle of a regular polygon, we can use the formula:
Central Angle = &frac{360}{n}
where n is the number of sides of the polygon.
In this case, we have a regular polygon with 25 sides, so we can plug that value into the formula:
Central Angle = &frac{360}{25}
Calculating this gives:
Central Angle = 14.4 degrees
Therefore, the measure of the central angle of a 25 sided regular polygon is 14.4 degrees.
