\n" ); document.write( "Draw out a right triangle with the following properties:
  • a = horizontal leg = x
  • b = vertical leg = height = x+146 (since it's 146 feet longer than the horizontal side)
  • c = hypotenuse = 250 ft string
We'll need the pythagorean theorem to tie together the three sides mentioned.
\n" ); document.write( "The goal is to find x, and then use that to compute x+146 to get the height.\r
