    Question

    A triangle has sides 7 cm, 24 cm, and 25 cm. Determine

    the largest angle in the triangle.
    A 90° Correct Answer Incorrect Answer
    B 120° Correct Answer Incorrect Answer
    C 135° Correct Answer Incorrect Answer
    D 150° Correct Answer Incorrect Answer

    Solution

    The sides 7 cm, 24 cm, and 25 cm form a right triangle (since 7² + 24² = 25², i.e., 49 + 576 = 625). Therefore, the largest angle is 90°, which is the angle opposite the hypotenuse. Correct answer: a) 90°
