Question

For a triangle with sides a=15 and b=8, side c must be less than what length? Numerical number preferable!

Answer 1

Use the pythagorean theorem.
a^2 + b^2 = c^2

Answer 2

It depends on if this angle is right angled or not, and if it is not right angled then it depends on the angle which is made by connecting side a and b.

Answer 3

Chaise is right. I'm assuming it's a right angle triangle.

Answer 4

The question that was given to me didn't state a specific kind of triangle, but that is what I'm assuming.
