Question: A right triangle has legs of 6 cm and 8 cm. Find the length of the hypotenuse. What is the length of the hypotenuse?
(A) 8 cm
(B) 10 cm
(C) 12 cm
(D) 14 cm
Solution:
The Pythagorean theorem states:
c²=a²+b²
where c is the hypotenuse. Substitute the values:
c²=6²+8²=36+64=100
Taking the square root:
c=√100=10 cm
