Decide whether the numbers can represent the side lengths of a triangle. :if they can, classify the triangle as right, acute, or obtuse--5,12,13

OpenStudy (anonymous):

5+12>13 (Valid) 12+13>5 (Valid) 13+5>12(Valid) All of those statements are valid, therefore you do have a triangle. I am not positive on how you can classify it though. :( so sorry!!!
