Question: In a right triangle, if one leg is 6 cm and the hypotenuse is 10 cm, what is the length of the other leg?

Options:

1. 8 cm
2. 7 cm
3. 5 cm
4. 4 cm

Correct Answer: 8 cm

Solution:

Using the Pythagorean theorem, a² + b² = c², we have 6² + b² = 10². Thus, 36 + b² = 100, leading to b² = 64, so b = 8 cm.
