use pythagorean thm:
\n" ); document.write( "h = sqrt( aa + bb )
\n" ); document.write( "28 = sqrt( 23^2 + b^2 )
\n" ); document.write( "28^2 = 23^2 + b^2
\n" ); document.write( "784 = 529 + b^2
\n" ); document.write( "b^2 = 784 - 529
\n" ); document.write( "b^2 = 255
\n" ); document.write( "---
\n" ); document.write( "b = 15.97 cm
