Question

The length of two sides of a right triangle are leg: 9 m and hypotenuse: 15 m. Find the length of the third side.

Answer 1

Length of Third Side = 12 m

Explanation:

You can use the Pythagorean Theorem to solve this: a² + b² = c² or c² - b² = a² in which a and b are legs, and c is the hypotenuse. We use the second equation to solve this: 15² - 9² = a² or 225 - 81 = a². This simplifies to 144 = a². To find a specifically, find the square root of 144, 12.
