In ABC AD=12 , AB=15,and AC=13 what is BC

Given:

A triangle ABC where AD = 12 units, AB = 15 units, and AC = 13 units.

To find:

The length of BC.

Solution:

According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.

There are 2 triangles, ACD and ABD in triangle ABC.

In triangle ACD, AC is the hypotenuse.

In triangle ABD, AB is the hypotenuse.

Assume the length of CD is x and the length of DB is y.

For triangle ACD,

For triangle ABD,

units.

So BC is option C. 14 units long.

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!
