A 17ft ladder is leaning against a house If the top of the lader is 15ft above the ground how far from the house is the bottom of the ladder?

Use the formula for calculating the lenght of the hypotenuse of a right triangle to solve. The formula is a² + b² = c² where a and b are the sides and c is the hypotenuse. The length of the hypotenuse is given as 17ft and the length of one of the sides is given 15ft. So, if a² + b² = c², then a² = c² - b². Use this formula to solve by substituting with the known values: a² = 17² - 15² a² = 289 - 225 a² = 64 a = 8 The bottom of the ladder is 8ft from the house.
