Respuesta :

72°

the sum of the exterior angles of a polygon = 360°

for a pentagon with 5 sides the

exterior angle = [tex]\frac{360}{5}[/tex] = 72°


Answer:

Measure of an exterior angle of a regular pentagon is 72°.

Step-by-step explanation:

Measure of an exterior angle of a regular polygon is calculated by

Exterior angle = [tex]\frac{360}{\text{Number of sides of the polygon}}[/tex]

                       = [tex]\frac{360}{n}[/tex]

If the regular polygon is a pentagon then measure of the exterior angle will be

= [tex]\frac{360}{5}[/tex]

= 72°

Therefore, measure of an exterior angle of a regular pentagon is 72°.
