To identify a Pythagorean triple, we need to find a set of three integers \( (a, b, c) \) such that \( a^2 + b^2 = c^2 \).
Let's check each option given:
-
(25, 60, 39):
- \( 25^2 + 60^2 = 625 + 3600 = 4225 \)
- \( 39^2 = 1521 \)
- Not a Pythagorean triple.
-
(50, 120, 130):
- \( 50^2 + 120^2 = 2500 + 14400 = 16900 \)
- \( 130^2 = 16900 \)
- This is a Pythagorean triple.
-
(15, 25, 39):
- \( 15^2 + 25^2 = 225 + 625 = 850 \)
- \( 39^2 = 1521 \)
- Not a Pythagorean triple.
-
(10, 12, 13):
- \( 10^2 + 12^2 = 100 + 144 = 244 \)
- \( 13^2 = 169 \)
- Not a Pythagorean triple.
The only option that forms a Pythagorean triple is (50, 120, 130).
