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.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
