Let the height of the glass = h. Using the sine function: Sin(a) = h/c where a = 60 degrees and c is the hypotenuse.
\n" ); document.write( " $\"sin%2860%29+=+h%2F20\"$
\n" ); document.write( " $\"h+=+20%2Asin%2860%29\"$
\n" ); document.write( " $\"h+=+20%280.866%29\"$
\n" ); document.write( " $\"h+=+17.32\"$ cm
\n" ); document.write( "The glass is 17 cm. tall. \n" ); document.write( "
