Answer:
[tex]\dfrac{TX}{XR}=\dfrac{ST}{RT}[/tex]
Step-by-step explanation:
In triangle RST, TX bisects angle RTS.
Angle bisector theorem 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:
[tex]\dfrac{TX}{XR}=\dfrac{ST}{RT}[/tex]
Therefore, option B is true.
