A 10-m ladder is leaning against a building. The bottom of the ladder is 5 m from the building. How high is the top of the ladder?
\n" ); document.write( ".
\n" ); document.write( "Apply Pythagorean's theorem:
\n" ); document.write( "Let H = height of top of ladder
\n" ); document.write( ".
\n" ); document.write( "H^2 + 5^2 = 10^2
\n" ); document.write( "H^2 + 25 = 100
\n" ); document.write( "H^2 = 75
\n" ); document.write( "H = sqrt(75)
\n" ); document.write( "H = 8.66 m
