Answer:

Step-by-step explanation:

Using the pythagorean theorem we have DE^2 + 5^2 = 13^2

DE^2 = 169 - 25 = 144

DE = sqrt144 = 12

Or, you could just remember the triangle 5-12-13, as it is pretty common, along with 3-4-5, 7-24-25

Find the distance between A(2, -9) and B(-5, 7) on a coordinate plane d=?

Kazeer [188]

Answer:

$d=17.4642$

Step-by-step explanation:

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

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(-5-2)^2+(7-(-9))^2}$

$d=\sqrt{(-7)^2+(7+9)^2}$

$d=\sqrt{49+(16)^2}$

$d=\sqrt{49+256}$

$d=\sqrt{305}$

$d=17.4642$
