Sara is building a triangular pen for her pet rabbit. if two of the sides measure 8 feet and 15 feet, what could the length of the third side be?

As the pen is a triangle, the third side can either be the hypotenuse or a regular side. If the third side is the hypotenuse, it's length would be  feet. If the third side is a regular side, than it would be ≈12.689 feet. This means your third side can either be 17 feet long or 12.689 feet long.

I’m not positive but i think it’s none of your buisness
