Question

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg?

Answer 1

We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.

c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet
