In a right-angled triangle, the lengths of the two legs are 6 cm and 8 cm. What is the length of the hypotenuse?
Answer: A
We use the Pythagorean theorem for a right-angled triangle: \(a^2 + b^2 = c^2\), where a and b are the legs and c is the hypotenuse.
\(6^2 + 8^2 = c^2\)
\(36 + 64 = c^2\)
\(100 = c^2\)
\(c = \sqrt{100} = 10\) cm.
