Step-by-step explanation:
[tex]In \: \triangle ABC, \: XY || BC. \\ \\
\therefore \: by \: Basic \: Proportionality \: Theorem: \\ \\ \frac{AX}{BX} = \frac{AY}{CY} \\ \\ \therefore \: \frac{AX}{8} = \frac{7}{10} \\ \\ \therefore \:AX = \frac{7}{10} \times 8 \\ \\ \therefore \:AX = \frac{56}{10} \\ \\ \huge \red{ \boxed{\therefore \:AX = 5.6 \: units}}[/tex]
Thus, option B) 5.6 is the correct answer.
