Answer:
The numbers 1-9 add up to 45.
The sum of all three sides = 45 + (3 corners),
since each corner contributes to two sides.
Sum of all three sides = 3 * one side.
(3 corners) = sum of all three sides - 45.
Since both terms on the right side are divisible by 3,
the sum of the three corners is divisible by 3 too.
That limits the choices for the corners.
The sum of each side then will be (45 + (3 corners))/3.
From there, exhaustive search reveals the solutions below.
Side = 17
Side = 19
Side = 19
