Answer:
10
Step-by-step explanation:
To calculate the distance d use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (- 5, - 8)
d = [tex]\sqrt{(-5+5)^2+(-8-2)^2}[/tex]
= [tex]\sqrt{0^2+(-10)^2}[/tex]
= [tex]\sqrt{0+100}[/tex] = [tex]\sqrt{100}[/tex] = 10
