Which regular polygon has a rotation of 240 degree to carry the polygon onto itself?

1 answer:

4 0

The regular polygon that has a rotation of 240 degrees to carry the polygon onto itself is the equilateral triangle.

<h3>The missing part of the question</h3>

<u>Options</u>

Equilateral triangle

Octagon

Rectangle

Pentagon

<h3>How to determine the polygon?</h3>

A polygon that can carry itself onto itself after a rotation of 240 degrees must obey the following rule:

Angle of rotation = 360/Sides

Next, we test the options:

Option (a) equilateral triangle

Angle of rotation = 360/3

Evaluate

Angle of rotation = 120

Next, we list the multiples of 120

120, 240, 360.....

See that 120 is a factor of 240.

This means that the equilateral triangle would be rotated onto itself when rotated by 240 degrees.

The perimeter of a rectangular toddler play area is 100 feet. The length is 10 feet more than 3 times the width. Find the length

Mekhanik [1.2K]

Answer:

length and width = 40 and 10 ft.

Step-by-step explanation:

The perimeter of a rectangular toddler play area is 100 feet.

Perimeter = 2(length + width)

Let the width = w

The length is 10 feet more than 3 times the width. Length = 10+(3w)

now put the values

100 = 2(10+3w + w)

100 = 2w + 20 + 6w

100 = (2w + 6w) + 20

100 = 8w + 20

8w = 100 - 20

w = $\frac{80}{8}$

w = 10 feet.

Now Length = 10+ (3w)

= 10+( 3 × 10)

= 10 + 30

= 40 feet

Therefore, length = 40 feet and width = 10 feet
