Answer:
11 units
Step-by-step explanation:
To calculate CD use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(- 4, 6) and (x₂, y₂ ) = D(- 4, - 5)
CD = ![\sqrt{(-4+4)^2+(-5-6)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4%2B4%29%5E2%2B%28-5-6%29%5E2%7D)
= ![\sqrt{0^2+(-11)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B0%5E2%2B%28-11%29%5E2%7D)
=
=
= 11
