Question

In right triangle ABC,

Answer 1

I'll start drawing the triangle

We have the following information:

AB = 13

BC = 5

With that is enough to draw.

To find the lenght of AC, since it is a right triangle we can use the Pythagorean Theorem.

Applying the Pythagorean Theorem we're going to have:

`\begin{gathered} 5^2+(AC)^2=13^2 \\ 25+(AC)^2=169 \\ (AC)^2=169-25 \\ AC=\sqrt[]{144}=12 \end{gathered}`

With this, we find the lenght of AC, it is equal to 12.

With these side lengths, we have what is called a 'Pythagorean triple'.
