A construction company plans to lean a 15ft ladder against a building from 7ft away. How far up the building will it reach?
A right triangle is created with a leg of 7 feet, hypotenuse of 15, and an unknown leg.
Pythagorean Theorem is a² + b² = c² a and b are the legs, and c is the hypotenuse 7² + b² = 15² {substituted into Pythagorean Theorem} 49 + b² = 225 {evaluated exponents} b² = 176 {subtracted 49 from each side} b ≈ 13.3 {took square root of each side} It will reach approximately 13.3 feet up the building.
