Answer:

see explanation

Step-by-step explanation:

Calculate AC and AB using the distance formula

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

with (x₁, y₁ ) = A(1,8) and (x₂, y₂ ) = C(4,2)

AC = $\sqrt{(4-1)^2+(2-8)^2}$

= $\sqrt{3^2+(-6)^2}$

= $\sqrt{9+36}$

= $\sqrt{45}$ = $\sqrt{9(5)}$ = 3 $\sqrt{5}$

Repeat with

(x₁, y₁ ) = A(1, 8) and (x₂, y₂ ) = B(2, 6)

AB = $\sqrt{(2-1)^2+(6-8)^2}$

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

= $\sqrt{1+4}$

= $\sqrt{5}$

So AB = $\sqrt{5}$ and AC = 3 $\sqrt{5}$

Thus

AC = 3AB
