State if the three side lengths form an acute, obtuse or right triangle 6, 2sqrt 55 and 17

That is a obtuse angle

If u see by pythagorean theorm

6^2+4*55=16

But here hypotenuse is 17 greater than 16.

Compare the hypotenuse to the longest side given in the problem. If the longest given side is shorter than the hypotenuse, the given triangle is acute. If it is longer than the hypotenuse, the given triangle is obtuse.

I am pretty sure it would form a acute angle!
