Question

Decide whether a triangle with side lengths of sqr5, 5, and 5.5 is right, acute, or obtuse.

Answer 1

Use this information.
If c^2 = a^2 + b^2, then it's a right triangle.
If c^2 > a^2 + b^2, then it's an obtuse triangle.
If c^2 < a^2 + b^2, then it's an acute triangle.
Where a = √5, b = 5, and c = 5.5

Answer 2

?

Answer 3

Where are you confused?

Answer 4

the whole thing.

Answer 5

Do you not know how to use the formula?

Answer 6

\[c^{2} ? a^{2} + b^{2}\]
Solve this using a = √5, b = 5, and c = 5.5
\[5.5^{2}?√5^{2} + 5^{2}\]
Just solve and see which is bigger.
