Answer:
x = 40
Step-by-step explanation:
Using similarity theorem, we have the following:
![\frac{24}{24 - 15} = \frac{x}{x - 25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B24%7D%7B24%20-%2015%7D%20%3D%20%5Cfrac%7Bx%7D%7Bx%20-%2025%7D%20)
Solve for x
![\frac{24}{9} = \frac{x}{x - 25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B24%7D%7B9%7D%20%3D%20%5Cfrac%7Bx%7D%7Bx%20-%2025%7D%20)
Cross multiply
![24(x - 25) = x(9)](https://tex.z-dn.net/?f=%2024%28x%20-%2025%29%20%3D%20x%289%29%20)
![24x - 600 = 9x](https://tex.z-dn.net/?f=%2024x%20-%20600%20%3D%209x%20)
Subtract 24x from each side
![- 600 = 9x - 24x](https://tex.z-dn.net/?f=%20-%20600%20%3D%209x%20-%2024x%20)
![- 600 = -15x](https://tex.z-dn.net/?f=%20-%20600%20%3D%20-15x%20)
Divide both sides by -15
40 = x
x = 40
