A rope 29 ft long rope is tied to the top of a flag pole. The rope is staked to the ground 21 ft away from the base of the pole. How tall is the flag pole?

Answers

Answer: 20 ft


Step-by-step explanation:

Given: The length of rope tied to the top of a flag pole=29 ft

The distance between base of the pole and the point on ground where the rope is stacked= 21 ft

Let x be the height of flagpole.

Now, we can see the figure that the given situation represents a right triangle

Where longest side= 29

By Pythagoras theorem of right triangle, the square of the longest side is equal to the sum of the squares of the other two sides.

29^2=21^2+x^2\n\Rightarrow\ x^2=29^2-21^2\n\Rightarrow\ x=841-441\n\Rightarrow\ x=400\n\Rightarrow\ x=√(400)\n\Rightarrow\ x=20

Hence, the height of flagpole = 20 ft.
It's like A2+B2=C2 so:
A2+B2=C2
A2+ 21(squared)=29(squared)
A2=441=841
A2=400
A=√(400)
A=20

Megan is putting wallpaper on a wall that measures 8 feet by 12 feet how much wallpaper does Meghan need to cover the wall

Answers

12*8 ( l * w ) = 96

Megan needs 96 feet squared of wallpaper to cover that wall.
Find the area (area=length*width)
area=8*12
area=96
as area is always expressed in units squared it would be 96ft squared (96 cubic feet)
