Answer:

DB = 8

Step-by-step explanation:

Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is

$\frac{DB}{DC}$ = $\frac{AD}{BD}$ , substitute values

$\frac{DB}{17.8-5}$ = $\frac{5}{BD}$

$\frac{DB}{12.8}$ = $\frac{5}{BD}$ ( cross- multiply )

DB² = 64 ( take the square root of both sides )

DB = $\sqrt{64}$ = 8
