Answer:

CD = 2 units

Step-by-step explanation:

in the given right triangle ΔCDE,

By applying tangent rule,

tan(∠E) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{\text{CD}}{\text{DE}}$

tan(30)° = $\frac{\text{CD}}{2\sqrt{3}}$

$\frac{1}{\sqrt{3}}=\frac{\text{CD}}{2\sqrt{3}}$

CD = $\frac{2\sqrt{3}}{\sqrt{3}}$

CD = 2 units

Therefore, CD = 2 unit will be the answer.
