    A 5 cm Correct Answer Incorrect Answer
    B 6 cm Correct Answer Incorrect Answer
    C 7 cm Correct Answer Incorrect Answer
    D 8 cm Correct Answer Incorrect Answer

    Solution

    Use the Pythagorean theorem: a² + b² = c² Where a and b are the legs, and c is the hypotenuse. Substitute the given values: 12² + b² = 13² 144 + b² = 169 b² = 169 - 144 b² = 25 b = √25 b = 5 cm Correct Option: a) 5 cm
