This gotten by Pythagoras theorem, with the formula stated as
hypotenuse² = opposite² + adjacent²
plugging the values as in the problem
50² = (√18)² + (√32)²
50² = 18 + 32
50² = 50 - incorrect
(√50)² = 6² + (√14)²
50 = 36 + 14
50 = 50 - correct
20² = 8² + 4²
400 = 64 + 16
400 = 80 - incorrect
6² = 5² + 4²
36 = 25 + 16
36 = 41 - incorrect
