Answer:
≈ 11.4
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)
d = [tex]\sqrt{(1-8)^2+(-2-7)^2}[/tex]
= [tex]\sqrt{(-7)^2+(-9)^2}[/tex]
= [tex]\sqrt{49+81}[/tex]
= [tex]\sqrt{130}[/tex]
≈ 11.4 ( to the nearest tenth )
