Supplementary angles add to 180 degrees.
\n" ); document.write( "Let the smaller angle=x
\n" ); document.write( "The larger angle is 4x+30
\n" ); document.write( "They add to 180 degrees.
\n" ); document.write( "Substitute.\r
\n" ); document.write( "\n" ); document.write( "x + (4x+30)=180\r
\n" ); document.write( "\n" ); document.write( "5x +30=180\r
\n" ); document.write( "\n" ); document.write( "subtract 30 from both sides.
\n" ); document.write( "5x=150.
\n" ); document.write( "Divide by 5 on both sides\r
\n" ); document.write( "\n" ); document.write( "x=30
\n" ); document.write( "4x+30=4(30) +30=150\r
\n" ); document.write( "\n" ); document.write( "The two angles are 30, and 150.
\n" ); document.write( "The given angle is 150. (answer the question!!!) Its supplementary angle is 30, and 150 is 30 more than 4 times 30.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
