Ineed it what side length would be possible for a triangle if you already know the other two lengths are 19cm and 32cm explain step by step

13 < n < 51

Explanation:

Basically to find the lowest possible length, all you need to do is subtract the lower number from the higher number (32 - 19), and to find the greatest possible length, add the lower number and the higher number (32 + 19). Then you'd plug it in to this inequality: a < n < b, a being the difference, and b being the sum. But, if the triangle were a right triangle that would be a whole different story.

i believe the answer is the polygon, heptagon.
