So, the shortest side is 13, the other two fellows are two consecutive values.... ok... let's say the other leg is "a", a consecutive value to that will be a+1, so the hypotenuse is "a + 1" then
check the picture below
and surely you'd know what "a" is
The 3rd one
You can factor 3 out of each term in the numerator. And then divide it by the 3 in the denominator.
