Answer:

x ≈ 2.57

Step-by-step explanation:

Δ ACB and Δ AED are similar, thus the ratios of corresponding sides are equal, that is

$\frac{CB}{ED}$ = $\frac{AB}{AD}$ , substitute values

$\frac{x}{6}$ = $\frac{3}{7}$ ( cross- multiply )

7x = 18 ( divide both sides by 7 )

x = $\frac{18}{7}$ ≈ 2.57 ( to 2 dec. places )
