GOOD AT MATH!! PLEASE HELPPP

Answer:
Option C
Step-by-step explanation:
We know that a right triangle can be solved using the pythagorean theorem. (a^2 + b^2 = c^2, where c= longest length) 5^2 + 8^2 does not equal 12^2. This triangle is not a right triangle.
Answer:
C
Step-by-step explanation:
the pythagorean theorem states that for a right triangle [tex]A^{2} +B^{2} =C^{2}[/tex]
and since [tex]5^{2} +8^{2} \neq 12^{2}[/tex]
it isn't a right triangle
plz mark me brainliest. :)
