Answer:
Option C.
Step-by-step explanation:
Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.
Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.
Using triangle proportionality theorem we get
![\dfrac{SA}{SB}=\dfrac{CT}{BT}](https://tex.z-dn.net/?f=%5Cdfrac%7BSA%7D%7BSB%7D%3D%5Cdfrac%7BCT%7D%7BBT%7D)
![\dfrac{SA}{10}=\dfrac{2.7}{9}](https://tex.z-dn.net/?f=%5Cdfrac%7BSA%7D%7B10%7D%3D%5Cdfrac%7B2.7%7D%7B9%7D)
On cross multiplication we get
![9\times SA=2.7\times 10](https://tex.z-dn.net/?f=9%5Ctimes%20SA%3D2.7%5Ctimes%2010)
![9SA=27](https://tex.z-dn.net/?f=9SA%3D27)
Divide both sides by 9.
![SA=3](https://tex.z-dn.net/?f=SA%3D3)
The length of SA is 3ft.
Therefore, the correct option is C.
