Question

I need to know how to find x

Answer 1

Answer:

x = $\frac{20}{3}$

Step-by-step explanation:

ΔABC and ΔEDC are similar triangles ( AA ), hence the ratios of corresponding sides are equal, that is

$\frac{AB}{ED}$ = $\frac{BC}{DC}$, substitute values

$\frac{x}{4}$ = $\frac{5}{3}$ ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = $\frac{20}{3}$
