Question

Hey puddin could ya help me !?- What is the length of segment AB?

Answer 1

AB = 4
`√(5)`

Explanation:

Calculate AB using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(0, 10)

AB =
`√((0-6)^2+(10-2)^2)`

=
`√(4^2+8^2)`

=
`√(16+64)`

=
`√(80)` = 4
`√(5)` ← exact length
