A 20 in (on the diagonal) TV has a width of 16 in. What is the height?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Using Pythagorean formula, \"a%5E2+%2B+b%5E2+=+c%5E2\" to find the height, and using H for height, we get: \"H%5E2+%2B+16%5E2+=+20%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"H%5E2+%2B+256+=+400\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"H%5E2+=+400+-+256\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"sqrt%28H%5E2%29+=+sqrt%28144%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, H or height = \"highlight_green%2812%29\"
\n" ); document.write( "
\n" );
