Answer:
![x = 7](https://tex.z-dn.net/?f=%20x%20%3D%207%20)
Step-by-step explanation:
According to the side-splitter theorem, the two sides of the triangle is divided proportionally if the line that intersects both sides is parallel to the third side of the ∆.
Therefore, based on this theorem, we would have the following:
![\frac{x}{21} = \frac{8}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B21%7D%20%3D%20%5Cfrac%7B8%7D%7B24%7D%20)
Solve for x
![\frac{x}{21} = \frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B21%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20)
Multiply both sides by 21
![\frac{x}{21}*21 = \frac{1}{3}*21](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B21%7D%2A21%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2A21%20)
![x = \frac{21}{3}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%7B21%7D%7B3%7D%20)
![x = 7](https://tex.z-dn.net/?f=%20x%20%3D%207%20)
