Respuesta :

Answer:

1. Use the Pythagorean theorem to find AD. Show your work.

AD=9

Side BD=12, and side AB=15. We know that side AB is the hypotenuse, so AD^2+144=225

225-144=81, so side AD=9

2. Find AC. Show your work.

AC=25

To find AC, we can add AD and DC

9+16=25

3. Is ΔABC a right triangle? Explain.

ABC is a right triangle because AB^2+BC^2=AC^2
