Answer:

The rotational angle of a regular polygon with 72 sides is 5º.

Step-by-step explanation:

The rotational angle ([tex]\theta[/tex]), measured in sexagesimal degrees, of polygon of [tex]n[/tex] sides is the angle of a complete revolution divided by the number of sides ([tex]n[/tex]). That is:

[tex]\theta = \frac{360}{n}[/tex] (1)

If we know that [tex]n = 72[/tex], the rotational angle is:

[tex]\theta = \frac{360}{72}[/tex]

[tex]\theta = 5^{\circ}[/tex]

The rotational angle of a regular polygon with 72 sides is 5º.
