Question

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

Answer 1

8.6 units

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 =
`√((8-1)^2+(1-6)^2)`

=
`√(7^2+(-5)^2)`

=
`√(49+25)`

=
`√(74)` ≈ 8.6
