Answer:

32

Step-by-step explanation:

[tex] \triangle ABC \sim \triangle XYZ[/tex] (given)

[tex] \therefore \frac{AB}{XY} = \frac{BC}{YZ} [/tex] (csst)

[tex] \therefore \frac{68}{17} = \frac{a}{8} [/tex]

[tex] \therefore 4= \frac{a}{8} [/tex]

[tex] \therefore 4(8)= a [/tex]

[tex] \therefore a = 32 [/tex]
