Question

a triangle has side lengths of 24 in, 32, in, and 40 in. is the triangle acute, obtuse, or right?

Answer 1

use pythag a^2 + b^2 = c^2

Answer 2

but how do i use that to see what kind of angle it is?

Answer 3

If c^2<a^2+b^2 the the triangle is acute
c^2 = a^2+b^2 it's right
c^2 > a^2+b^2 obtuse

Where a, b, c are the different sides of the triangle

Answer 4

a^2 > b^2 + c^2 where a is longest side
- if that is true then the triangle is obtuse

Answer 5

In my equations, c is the longest side

Answer 6
