What is the length of BC round to the nearest 10th of a unit

Answer:
8.6 units
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = B(1, 6) and (x₂, y₂ ) = C(8,1)
d = [tex]\sqrt{(8-1)^2+(1-6)^2}[/tex]
= [tex]\sqrt{7^2+(-5)^2}[/tex]
= [tex]\sqrt{49+25}[/tex]
= [tex]\sqrt{74}[/tex] ≈ 8.6
