Find the length of CD

laiz [17]

Answer:

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = C(3, - 2) and (x₂, y₂ ) = D(7, - 8)

CD = $\sqrt{(7-3)^2+(-8+2)^2}$

= $\sqrt{4^2+(-6)^2}$

= $\sqrt{16+36}$

= $\sqrt{52}$ ≈ 7.2 → D
