Answer:
5, 10, 11
Step-by-step explanation:
You could actually solve this problem 2 ways. You could use the pythagorean theorem, if you could confirm it was a right triangle.
But since they give you the perimeter, that will be the easy way.
Perimeter means all the sides added together will be 26
(x) + (x+5) + (2x+1) = 26
Now combine like terms
4x + 6 = 26
Subtract 6 from both sides
4x = 20
Divide both sides by 4
x = 5
Now we can plug the x back in the find the length of each side
(5) = 5
(5) + 5 = 10
2(5) + 1 = 11
