Answer:

$\huge \boxed{\mathrm{10.3 \ units}}$

Explanation:

To solve for CD, we can create a right triangle.

Where CD becomes the hypotenuse.

The length of the base of the triangle is 9 units.

The length of the height of the triangle is 5 units.

Apply Pythagorean theorem to solve for the hypotenuse.

$\sf hypotenuse = √((base )^2 +(height )^2 )$

c=√(9^2 +5^2 )

c=√(106)

$c \approx 10.29$
