A. Both rotational and reflectional.

Step-by-step explanation:

We have been given an image of a regular polygon. We are asked to determine type(s) of symmetry for our given polygon.

Upon looking at our given polygon, we can see that it is a pentagon.

We know that a regular pentagon has five equal sides and five lines of symmetry.

We can see that each line of symmetry divides pentagon into two mirror images, therefore, our given pentagon has reflectional symmetry.

We know that the regular polygon has a rotational symmetry. We can find rotational symmetry of a regular polygon by multiplying 360 degrees by number of sides.

$\text{Rotational symmetry of pentagon}=\frac{360^{\circ}}{5}$

$\text{Rotational symmetry of pentagon}=72^{\circ}$

Therefore, a regular pentagon has rotational symmetry.

The image is an example of both rotational and reflectional symmetry.

The image given in the picture is that of a regular polygon. The polygon is also a pentagon because it has five equal sides and 5 equal angles.

Further Explanation

From the image, each of the symmetry divides the pentagon into two mirror images, which shows that the pentagon has refectional symmetry.

For more clarification, reflectional symmetry refers to a type of rigid motion for a 2 D shape, it is also known as line symmetry, simplest symmetry or mirror symmetry.

Reflectional symmetry is very easy to see simply because one half is the reflection of the other half.

The polygon has a rotational symmetry; rotational symmetry of any polygon can be determined by dividing 360 degree by the number of sides. The central angle of any regular polygon is 360 degree divided by the number of sides and since a pentagon has 5 sides, therefore the normal calculation will be 360 divided by 5, which is 72 degree.

Rotational symmetry is when a shape is rotated around a central point and still remains the same. This implies, a shape is said to have rotational symmetry if can be turned around a fixed point and fits the space it originally occupied.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
