Find the distance CD rounded to the nearest tenth

motikmotik

Answer:

CD ≈ 15.0

Step-by-step explanation:

calculate CD using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = C (7, - 4) and (x₂, y₂ ) = D (- 8, - 5)

CD = $\sqrt{(-8-7)^2+(-5-(-4))^2}$

= $\sqrt{-15)^2+(-5+4)^2}$

= $\sqrt{225+(-1)^2}$

= $\sqrt{225+1}$

= $\sqrt{226}$

≈ 15.0 ( to the nearest tenth )
