Question

Consider : • A (-3,-4) • B (5,2) • C (11,-6) What is BC ?

Answer 1

BC is 10 units.

Further explanation:

Given:

A (-3,-4)

B (5,2)

C (11,-6)

BC means we have to find the length or magnitude of BC.

The distance formula will be used to calculate the magnitude.

The distance formula is:

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

In the given scenario,

(x1, y1) = (5,2)

(x2,y2) = (11,-6)

Putting the values in the formula

$BC = \sqrt{(11-5)^2+(-6-2)^2}\\BC = \sqrt{(6)^2+(-8)^2}\\BC = \sqrt{36+64}\\= \sqrt{100}\\ = 10\ units$

So, BC is 10 units.
