Answer:
35, 31, 25, 18
Step-by-step explanation:
10 x 7/2 = 35
10 + 7 + 14 = 31
8 1/3 x 6/2 = 25
4 1/3 + 5 1/3 + 8 1/3 = 18
Answer: 20 feet.
Step-by-step explanation:
Observe the right triangle attached.
You need to find the value of "x".
Then, you can use the Pythagorean Theorem:
![a^2=b^2+c^2](https://tex.z-dn.net/?f=a%5E2%3Db%5E2%2Bc%5E2)
Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.
In this case, you can identify that:
![a=25ft\\b=15ft\\c=x](https://tex.z-dn.net/?f=a%3D25ft%5C%5Cb%3D15ft%5C%5Cc%3Dx)
Substitute these values into
:
![(25ft)^2=(15ft)^2+x^2](https://tex.z-dn.net/?f=%2825ft%29%5E2%3D%2815ft%29%5E2%2Bx%5E2)
Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:
![x^2=(25ft)^2-(15ft)^2](https://tex.z-dn.net/?f=x%5E2%3D%2825ft%29%5E2-%2815ft%29%5E2)
![x=\sqrt{(25ft)^2-(15ft)^2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B%2825ft%29%5E2-%2815ft%29%5E2%7D)
![x=20ft](https://tex.z-dn.net/?f=x%3D20ft)
