If the smallest angle of rotation for a regular polygon is 18°, how many sides does polygon have? 10
12
20
24

Thank you for asking this question. Here is your

The sum of angles is 360°

Now we will divide 360 with the number of sides the polygon has.

360/18

= 20

So that means the polygon has 20 sides.

The final answer for this question is 20.

If there is any confusion please leave a comment below.Also Kindly mark as BRAINLIEST.

The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself. The order of symmetry is the number of times the figure coincides with itself as its rotates through 360° . Example: A regular hexagon has rotational symmetry.

Consider the regular pentagon ABCDE, with center (of mass) O. The central angle O is a complete angle, so its measure is 360°. It is divided into 5 equal parts, so each of them has a measure of 360°/5=72°.

Step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
