Answer:
[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (4, 7)
d = [tex]\sqrt{(4-2)^2+(7-8)^2}[/tex]
= [tex]\sqrt{2^2+(-1)^2}[/tex]
= [tex]\sqrt{4+1}[/tex]
= [tex]\sqrt{5}[/tex] ≈ 2.24 ( to 2 dec. places )
