Question 172406
The base of a 15-ft ladder is 8 feet away from the wall. How far above the floor is the top of the ladder? Give answer to the nearest thousandth.
----------------------
Assuming the wall doesn't lean, it's a right triangle.
The ladder is the hypotenuse.
{{{x^2 = 15^2 - 8^2}}}
{{{x^2 = 161}}}
x =~ 12.689 feet
