Answer:
The correct option is 1.
Step-by-step explanation:
If an angle bisector divides a triangle in two parts, then the line segments of that side will have the same ratio as the other sides of the triangle.
[tex]\frac{20.1}{x}=\frac{17.5}{7.5}[/tex]
[tex]20.1\times 7.5=x\times 17.5[/tex]
[tex]x=\frac{20.1\times 7.5}{17.5}[/tex]
[tex]x=8.61429[/tex]
[tex]x\approx 8.6[/tex]
Therefore option 1 is correct.
