Question

pythagorean trile
1
2
400

Answer 1

4-12-20 is not a Pythagorean trile because

4^2 + 12^2 is NOT equal to 20^2

16 + 144 is NOT equal to 400

160 is NOT equal to 400

Answer 2

All other triplets are Pytagorean triplets.

Answer 3

The second question: 8^2 + 12^2 = x^2
64 + 144 = x^2
208 = x^2
x = sqrt(208)

Answer 4
