Question

A triangle has side lengths 10, 15, and 7. Is the triangle acute, obtuse, or right? Explain

Answer 1

All I know is that its not obtuse and that i think its right.

Answer 2

10^2+15^2=17^2
100+225=289
325=289
Nope. It's not a right triangle.

Answer 3

If it were a right triangle, the hypotenuse would be sqrt325 or 18
Since the long side is less than 18, the triangle is acute.
