The exterior angles of a regular pentagon has a measure of 360-108= 252 degrees
the sum of these exterior angles will be 5*252=1260 degrees
a regular nonagon (9-gon) has the exterior angles measure of 360 -140 = 220 degrees
the sum of these exterior angles of a nonagon will be equal 9*220=1980 degrees
so from these result that
the sum of the measures of the exterior angles of a regular 5-gon is less than the sum of the measures of the exterior angles of a 9-on
hope this will help you
ANSWER
96 yd
EXPLANATION
Let the width of the rectangle be w, then, the length of the rectangle will be:
The area of a rectangle is calculated using the formula:
It was given that, the area of the rectangle is 320yd²
Divide both sides by 5.
Take square root of both sides to get:
This means the length is
The perimeter of a rectangle is given by:
P=2(w+l)
We plug in the values to get:
The perimeter is 96yd
Answer:
Step-by-step explanation:
Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;
Area of rectangle = Length * Width
Area of the rectangular backyard = 18yards * 16yards
Area of the rectangular backyard = 288yards²
If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²
The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool
The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²
<em>Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use</em>. The area needed for the tiles for the rest of the backyard is therefore 263yd².
Amount of tiles needed to buy can be expressed as 263/dimension of a tile.
Answer:
- To solve the following equation we must first combine like terms
- Recognize the easiest way to manipulate the equation
- Lastly rearrange to isolate for x: usually done with division
2x+3x-11x-6=0
Combine like x variables
-6x-6=0
Add 6 to the right side
-6x = 6
Divide by -6
x=-1
