One leg of a right triangle measures 3 centimeters and the other leg measures 6 centimeters, what is the length of the hypotenuse in centimeters?

A. 3 5

B. 5 3

C. 5

D. 9

From the information given, the leg of the triangle measures 3 cm and the other leg measures 6 cm. The length of the hypotenuse is unknown.

Let the hypotenuse be c

Let one leg of the triangle be a

Let the other leg of the triangle be b

We use the formula : c² = a² + b²

c² = 3² + 6²

c² = 9 + 36

c² = 45

c = √45

c = 6.70

Therefore, the length of the hypotenuse is 6.7 cm
