Answer:
12 meters
Step-by-step explanation:
Given That :
Length of ladder = 15m
Height of wall =. 9 m
Using Pythagoras rule :
Adjacent² = hypotenus² - opposite²
Adjacent² = 15² - 9²
Adjacent² = 225 - 81
Adjacent² = 144
Adjacent = sqrt(144)
Adjacent, x = 12
we are given
![x^2y-2xy-24y=y(x^2-2x-24)](https://tex.z-dn.net/?f=x%5E2y-2xy-24y%3Dy%28x%5E2-2x-24%29)
now, we can factor out right side term
![x^2-2x-24=x^2-6x+4x-6*4](https://tex.z-dn.net/?f=x%5E2-2x-24%3Dx%5E2-6x%2B4x-6%2A4)
![x^2-2x-24=(x-6)(x+4)](https://tex.z-dn.net/?f=x%5E2-2x-24%3D%28x-6%29%28x%2B4%29)
now, we can plug back
and we get
so,

According to the Pythagorean theorem the square of the hypotenuse (c) is the sum of the squares of the legs (a and b):
c² = a² + b²
We have:
a = 3x
b = 15
c = 3x + 3
Now, let's replace these parameters:
c² = a² + b²
(3x + 3)² = (3x)² + 15²
(3x)² + 2 * 3x * 3 + 3² = 9x² + 225
9x² + 18x + 9 = 9x² + 225
Rearrange:
9x² - 9x² + 18x = 225 - 9
18x = 216
x = 216 / 18 = 12
