\n" );
document.write( "Right Triangle with hypotenuse = 12cm        
\n" );
document.write( "Let x represent length  of side opposite the 30° angle
\n" );
document.write( "  sin 30° = opposite/hypotenuse 
\n" );
document.write( "  sin 30°  = 1/2
\n" );
document.write( "    cross multiply to solve for x
\n" );
document.write( "      2x = 12cm
\n" );
document.write( "       x = 6cm\r
\n" );
document.write( "\n" );
document.write( " Sides opposite 30°----- 60°-----90° triangle do have a ratio relationship:
\n" );
document.write( "                1 ::2
\n" );
document.write( " That is: knowing this, 6cm would have been a quick response, for ex.
