Since the sum of the exterior angles of any polygon is going to always be 360 u can take 360 and divide that by the number of sides which is 7. This gives u 51.4 degrees rounded to the nearest tenth for each exterior angle. PS. Roblox Rocks
Answer:
a’s average speed is 60km/h
Step-by-step explanation:
x = a’s average speed
60/40 = 90/x
Cross multiplication:
60x = 40x90
60x=3600
Divide both sides by 60
x= 60

∴
Step-by-step explanation:
4 H (Hundreds)
5 T(tens)
9 ones
3x3= 9
50x3= 150
100x3= 300
add 300+150+9= 459
The area of a 2D form is the amount of space within its perimeter. The length of the rectangle is 29 inches and the width of the rectangle is 12 inches.
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Let the width of the sheet be represented by x and the length be represented by y.
Area = x × y
348 = xy
x = 348/y
Perimeter = 2(x+y)
82 = 2(x+y)
41 = x + y
41 = (348/y) + y
0 = y² - 41y + 348
y = 29, 12
Therefore, the length of the rectangle is 29 inches and the width of the rectangle is 12 inches.
