If the smallest angle of rotation for a regular polygon is 18 how many sides does polygon have

 The number of sides of the given polygon is 20.

Step-by-step explanation:  Given that the smallest angle of rotation for a regular polygon is 18.

We are to find the number of sides of the polygon.

We know that

if α is the smallest angle of rotation for a polygon, then the number of sides f the polygon is given by

For the given polygon, we have

smallest angle of rotation, α = 18°.

Therefore, the number of sides of the polygon will be

Thus, the number of sides of the polygon is 20.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
