Answer:
a. 28.8
Step-by-step explanation:
Using the theorem of similarity, the following equation can be generated:
![\frac{x}{12} = \frac{25 + 35}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B12%7D%20%3D%20%5Cfrac%7B25%20%2B%2035%7D%7B25%7D%20)
Solve for x
![\frac{x}{12} = \frac{60}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B12%7D%20%3D%20%5Cfrac%7B60%7D%7B25%7D%20)
Cross multiply
![x*25 = 60*12](https://tex.z-dn.net/?f=%20x%2A25%20%3D%2060%2A12%20)
![25x = 720](https://tex.z-dn.net/?f=%2025x%20%3D%20720%20)
Divide both sides by 25
x = 28.8
