For a triangle with sides a, b and c, what is the range of the length of side c? a = 15, b = 8, c = _____<c<_____
However, this is correct: \[|a-b|<c<|b-a|\]
if Hero's mathematical definition puzzles you, basically what it means is that the side c is longer than either side minus the other. The side is also shorter than the sum of the others
it was right !! thank you :D
