\n" ); document.write( "one leg of a right triangle and
\n" ); document.write( "the distance from the stake to the wall as the
\n" ); document.write( "other leg of the right triangle.
\n" ); document.write( "The length of the rope is the hypoteneuse
\n" ); document.write( "The pythagoran theorem is:
\n" ); document.write( " $\"h%5E2+=+a%5E2+%2B+b%5E2\"$
\n" ); document.write( " $\"39%5E2+=+15%5E2+%2B+b%5E2\"$
\n" ); document.write( " $\"1521+=+225+%2B+b%5E2\"$
\n" ); document.write( " $\"b%5E2+=+1296\"$
\n" ); document.write( " $\"b+=+36\"$
\n" ); document.write( "The building is 36 feet tall
