Venus shares a similar size, surface composition, and has an atmosphere with a complex weather system. Venus is different from Earth because it spins the opposite direction of Earth and it’s rotation is very slow.
Answer:
![y = 4.36](https://tex.z-dn.net/?f=y%20%3D%204.36)
Explanation:
Let the height of the ladder be L
![L = 10](https://tex.z-dn.net/?f=L%20%3D%2010)
Also:
- Let
![x = distance\ from\ the\ base\ of\ the\ ladder](https://tex.z-dn.net/?f=x%20%3D%20distance%5C%20from%5C%20the%5C%20base%5C%20of%5C%20the%5C%20ladder)
- Let
![y = height\ of\ the\ base\ of\ the\ ladder](https://tex.z-dn.net/?f=y%20%3D%20height%5C%20of%5C%20the%5C%20base%5C%20of%5C%20the%5C%20ladder)
When the ladder leans against the wall, it forms a triangle and the length of the ladder forms the hypotenuse.
So, we have:
--- Pythagoras Theorem
When the base is 9ft from the wall, this means that:
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
Substitute 9 for x and 10 for L in ![L^2 = x^2 + y^2](https://tex.z-dn.net/?f=L%5E2%20%3D%20x%5E2%20%2B%20y%5E2)
![10^2 = 9^2 + y^2](https://tex.z-dn.net/?f=10%5E2%20%3D%209%5E2%20%2B%20y%5E2)
![100 = 81 + y^2](https://tex.z-dn.net/?f=100%20%3D%2081%20%2B%20y%5E2)
Make
the subject
![y^2 = 100 - 81](https://tex.z-dn.net/?f=y%5E2%20%3D%20100%20-%2081)
![y^2 = 19](https://tex.z-dn.net/?f=y%5E2%20%3D%2019)
Make y the subject
![y = \sqrt{19](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%7B19)
![y = 4.36](https://tex.z-dn.net/?f=y%20%3D%204.36)
<em>Hence, the true distance at that point is approximately 4.36ft</em>
Sry i was knowing the answer i forgot ;(
