Answer:
5[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (1, - 2) and (x₂, y₂ ) = (2, 5)
d = [tex]\sqrt{(2-1)^2+(5+2)^2}[/tex]
= [tex]\sqrt{1^2+7^2}[/tex] = [tex]\sqrt{50}[/tex] = 5[tex]\sqrt{2}[/tex]
