Answer 1

Answer:

D

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AD}{CD}$ = $\frac{BD}{AD}$ , substitute values

$\frac{x}{13}$ = $\frac{3}{x}$ ( cross- multiply )

x² = 39 ( take the square root of both sides )

x = $\sqrt{39}$ → D
