Answer:
No, is not a Pythagorean triple
Explanation:
To know if you can build a right triangle with those sides we have to make the following equality
h² = l1² + l2²
The hypotenuse is always the longest side so it should be 30
we check the equality of the equation
30² = 14² + 22²
900 = 196 + 484
900 = 680
Equality was not fulfilled so it is a right triangle
