Well I don't know !
Let's work it out.
IF the triangle IS a right triangle, then
(the shortest side)² + (the medium side)² = (the longest side)²
Let's test this one:
(14)² = 196
(17)² = 289
(the shortest side)² + (the medium side)² = (196 + 289) = 485
(The longest side)² = (30)² = 900 .
900 is not the same number as 485,
so these three sides do not make a right triangle.
