Answer:
The rotational angle of a regular polygon with 72 sides is 5º.
Step-by-step explanation:
The rotational angle (
), measured in sexagesimal degrees, of polygon of
sides is the angle of a complete revolution divided by the number of sides (
). That is:
(1)
If we know that
, the rotational angle is:


The rotational angle of a regular polygon with 72 sides is 5º.
Answer:
3
Step-by-step explanation:
Points A and B lie on the horizontal line y = 1. The length of segment AB is then the difference of the x-coordinates of the points:
5 -2 = 3
The length of side AB is 3 units.
