Question

BRAINLY!!!- if a=7, b=8, and c=9.2 is this a right triangle? why?

Answer 1

Answer:

no

Step-by-step explanation:

If this were a right triangle we would assume the Pythagorean Theorem to prove it

$a^{2} +b^{2} =c^{2}$

$7^{2} +8^{2} =9.2^{2}$

this gives us

49+64=84.64

this is 143=84.64 and therefore not equal and not a right triangle
