i am working on these proof by exhaustion questions and i don't understand since they seem so vague.
Can you give an example of a question you're confused by? It's much easier to help that way.
EDIT: There's something wrong with your attachment. Maybe try inserting it as an image instead?

For the first one you're trying to work out how many triangles have perimeter 11 and all integer sides. There aren't many ways to make 11 out of three integers - if you make a list of all of them and exclude the ones that you can't make a triangle out of you'll know how many triangles there are.
