Answer 2

Dear malehumanoid:
First and foremost: What does "obtuse triangle" mean? We've got to undrstand that.

Answer 3

I believe it is a triangle with an angle greater than 90 degrees

Answer 4

I think it's C.. but thanks for the help.

Answer 5

it's indeed C

Answer 6

if x = 4 or 5, no triangles can be formed.
If x = 6,
6^2 + 5^2 < 10^2, which is obtuse

if x = 11,
5^2 + 10^2 > 11^2, which is a acute
