The measure of an angle is 2/3 the measure of its supplement. Find the measure
\n" ); document.write( "of the angle and its supplement.\r
\n" ); document.write( "\n" ); document.write( "let one angle be = x
\n" ); document.write( "then its supplement =( 180-x)\r
\n" ); document.write( "\n" ); document.write( "according to the sum we have \r
\n" ); document.write( "\n" ); document.write( "x = 2/3 (180-x)\r
\n" ); document.write( "\n" ); document.write( "x = 2/3*180 - 2/3*x\r
\n" ); document.write( "\n" ); document.write( "x = 2*60-2/3x\r
\n" ); document.write( "\n" ); document.write( "x+2/3*x= 120-2/3*x+2/3*x\r
\n" ); document.write( "\n" ); document.write( "3x+2x/3 = 120\r
\n" ); document.write( "\n" ); document.write( "5x/3*3= 120*3\r
\n" ); document.write( "\n" ); document.write( "5x = 360\r
\n" ); document.write( "\n" ); document.write( "5x/5 = 360/5\r
\n" ); document.write( "\n" ); document.write( "x = 72 degrees\r
\n" ); document.write( "\n" ); document.write( "the supplement angle = 180-72 = 108 degrees\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
