A rectangular swimming pool measures 40 ft by 60 ft and is surrounded by a path of uniform width around the four edges. The peri

Answer:

6ft

Step-by-step explanation:

Lets x = the width of the path the surrounding path will add 2x to the pool dimension,therefore over all dimesion: (2x+40) by (2x+60) the overall perimeter (2x + 40) + 2(2x+60) = 248 Simplify divide by 2, result (2x+40) +(2x+60) = 124

 Combine like terms 2x + 2x +40 +60 =124 

4x + 100 = 124 

4x=124 = 100

4x=24

x=24/4

x= 6ft is the width of the path

check this by finding the perimeter with these values; 2x = 12 ft 

2 ( 12 + 40 ) + 2( 12 +60 ) 

2( 52 + 2(72)

104 + 144 = 248; confirms our solution of x= 6 ft

The interior of a regular polygon is 5 times the exterior angle

densk [106]

Step-by-step explanation:

The interior angle of a polygon is given by

$\frac{(n - 2) \times 180}{n}$

The exterior angle of a polygon is given by

$\frac{360}{n}$

where n is the number of sides of the polygon

The statement

The interior of a regular polygon is 5 times the exterior angle is written as

$\frac{(n - 2) \times 180}{n} = 5( \frac{360}{n} )$

Solve the equation

That's

$\frac{180n - 360}{n} = \frac{1800}{n}$

Since the denominators are the same we can equate the numerators

That's

180n - 360 = 1800

180n = 1800 + 360

180n = 2160

Divide both sides by 180

The interior angle of the polygon is

$\frac{(12 - 2) \times 180}{12} = \frac{10 \times 180}{12} \\ = \frac{1800}{12}$

The answer is

Interior angle + exterior angle = 180

From the question

Interior angle = 150°

So the exterior angle is

Exterior angle = 180 - 150

We have the answer as

The polygon has 12 sides

The name of the polygon is

<h2>Dodecagon</h2>

Hope this helps you.
