Answer:
![\dfrac{TX}{XR}=\dfrac{ST}{RT}](https://tex.z-dn.net/?f=%5Cdfrac%7BTX%7D%7BXR%7D%3D%5Cdfrac%7BST%7D%7BRT%7D)
Step-by-step explanation:
In triangle RST, TX bisects angle RTS.
<u>Angle bisector theorem</u> says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
Hence, TX divides side RS in the ratio:
![\dfrac{TX}{XR}=\dfrac{ST}{RT}](https://tex.z-dn.net/?f=%5Cdfrac%7BTX%7D%7BXR%7D%3D%5Cdfrac%7BST%7D%7BRT%7D)
Therefore, option B is true.
