A carpenter used a 15.2 feet timber to brace a wall frame 5 feet high. If the construction site is level, what is the distance the timber will extend out from the wall?
A right triangle is formed with the timber and the wall. Therefore, you can use the Pythagorean Theorem to find the distance the timber extends out from the wall.
Pythagorean Theorem a² + b² = c² a and b are the legs c is the hypotenuse {the side across from the right angle} a² + b² = c² {pythagorean theorem} 5² + b² = 15.2² {substituted 5 in for a, a leg, and 15.2 in for c, the hypotenuse} 25 + b² = 231.04 {evaluated the exponents} b² = 206.04 {subtracted 25 from each side} b = 14.35 {took the square root of each side} The timber will extend out approximately 14.35 feet from the wall.
