tia_tia [17]

Answer:

<h2>11.4</h2>

Solution,

∆ ACB = ∆ EFD

finding the value of X,

$\frac{x}{3.8} = \frac{15}{5}$

Apply cross product property

$x \times 5 = 15 \times 3.8$

Calculate the product

$5x = 57$

Divide both sides by 5

$\frac{5x}{5} = \frac{57}{5}$

Calculate

$x = 11.4$

Hope this helps...
