<h3>answer.</h3>

•given that is smallest angle of rotational symmetry for a regular polygon is 30

•we have to find the number of side does the regular polygon have

•if we can rotate of figure around a center point be fewer than 360° and the figure appears and change then the figure has the rotation symmetry

<h3>Hence,12 number of sides the polygon.</h3>

no. of side= 360/ smallest angle at centre=12

Work: x+4/x=45
×x both sides
X+4= 45X
-X both sides
4=45x-x
4=44x
÷44 both sides
X=1/11
Answer: x=1/11
Check your work:
1/11+4/1/11=45
1/11+44/11/(1/11)=45
45/11÷1/11=45
45/11×11/1=45
45=45

The perimeter of the following figure is 18.6 inches. What is the length of n?

Valentin [98]

Given:

Perimeter of the figure = 18.6 inches

To find:

The length of n.

Solution:

Perimeter of the figure = 18.6 inches

Perimeter = Sum of the sides

3 + 6.3 + 4.5 + n = 18.6

13.8 + n = 18.6

Subtract 13.8 from both sides.

13.8 + n - 13.8 = 18.6 - 13.8

n = 18.6 - 13.8

n = 4.8

The length of n is 4.8 inch.

(I also converted my work into a google doc, so I'll attach that since it's quite difficult to type out steps on brainly. Especially with fractions and trying to make the steps look clean and easy to read. But I hope this helps and thanks for telling me about the problem when I asked.)

Don't hesitate to message me if you have any other math questions. I'd be happy to help. :D
