Two Angles are Supplementary if they add up to 180 degrees
\n" ); document.write( " ley x,y be the supplementary angles
\n" ); document.write( " x+y=180.............eq(1)
\n" ); document.write( " an angle is 20 degrees less than thrice its supplement
\n" ); document.write( " x= 3*y-20
\n" ); document.write( " put x =3y-20 in x+y=180
\n" ); document.write( " (3y-20)+ y =180
\n" ); document.write( " 3y+y-20=180
\n" ); document.write( " 4y-20 = 180
\n" ); document.write( " move -20 to the right
\n" ); document.write( " 4y =180+20
\n" ); document.write( " 4y =200
\n" ); document.write( " divide with 4 on both sides
\n" ); document.write( " $\"+4y%2F4=200%2F4\"$
\n" ); document.write( " y =50
\n" ); document.write( " x= 3*50-20
\n" ); document.write( " =150-20
\n" ); document.write( " =130
\n" ); document.write( "so x=130
\n" ); document.write( " y= 50
\n" ); document.write( " ration x: y = 130:50
\n" ); document.write( " =13:5
\n" ); document.write( " Result : ratio =13:5 \n" ); document.write( "

\n" );
