Answer:
sides 1 and 2 would have to be 8 and side 3 would be 15
Step-by-step explanation:
Looking at the problem since two sides have to be equal that means that their sum cannot be over 20 since that would make the triangle above its actual perimeter
So looking at numbers 1-9 and seeing which ones can add up to something like 9+2 or 6+5, that would add to eleven with one number being less
16 works since it can add to 15 (2*8 -1) and make 31
