\n" ); document.write( "\n" ); document.write( "15x = 180\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 180/15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7x = 7*12 = 84\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The largest angle is 84 degrees.
