given the side measures below determine whether or not triangle is acute right or obtuse 12 9 13

Respuesta :

Hi there!

Let's use the pythagorean theorem to figure this out.

WORK:
[tex] {12}^{2} + {9}^{2} = {13}^{2} [/tex]
[tex]144 + 81 = 169[/tex]
[tex]225 > 169[/tex]
The triangle is ACUTE.

Hope this helps!! :)
