To verify which of the given triples is another Pythagorean triple, we can use the Pythagorean theorem, which states that in a right triangle with sides \( a \) and \( b \), and hypotenuse \( c \), the following equation holds:
\[ a^2 + b^2 = c^2 \]
Let's check each of the options:
-
(25, 60, 39)
- \( 25^2 + 60^2 = 625 + 3600 = 4225 \)
- \( 39^2 = 1521 \)
- Since \( 4225 \neq 1521 \), this is not a Pythagorean triple.
-
(10, 12, 13)
- \( 10^2 + 12^2 = 100 + 144 = 244 \)
- \( 13^2 = 169 \)
- Since \( 244 \neq 169 \), this is not a Pythagorean triple.
-
(15, 25, 39)
- \( 15^2 + 25^2 = 225 + 625 = 850 \)
- \( 39^2 = 1521 \)
- Since \( 850 \neq 1521 \), this is not a Pythagorean triple.
-
(50, 120, 130)
- \( 50^2 + 120^2 = 2500 + 14400 = 16900 \)
- \( 130^2 = 16900 \)
- Since \( 16900 = 16900 \), this is a valid Pythagorean triple.
The correct answer is (50, 120, 130).
