Tommy is trying to find the length of one of the sides of the sail on the sailboat. One of the legs are 10 feet long and the hypotenuse is 13 feet long. What is the length of the other leg?

Respuesta :

Since it is a right triangle, we are use the Pythagoras' Theorem to find the missing leg.

a² + b² = c²

10² + b² = 13²

b² = 13² - 10²

b² = 169 - 100

b² = 69

b = 8.31 feet (nearest hundredth)

Answer: The other leg is 8.31 feet
