Question

1. A triangle has side lengths of 24 in., 32 in., and 40 in. Is the triangle acute, obtuse, or right? (1 point)
right
obtuse
acute

Answer 1

I presume you know of the Pythagorean theorem?
\(a^2+b^2 = c^2\) \(\Rightarrow\) Right Triangle
\(a^2+b^2 > c^2\) \(\Rightarrow\) Acute Triangle
\(a^2+b^2 < c^2\) \(\Rightarrow\) Obtuse Triangle
There is a special rule for the right triangle though; C must always be the longest side.
I assume you can plug in values and figure out the rest? If not do not be scared to ask me for more help :-).
