Supplemental means that the sum of the 2 angles is 180 degrees
\n" ); document.write( ".
\n" ); document.write( "If one angle is \"x\" ,,,the other angle is \"180-x\"
\n" ); document.write( ".
\n" ); document.write( "ratio = x/(180-x) = 7/8
\n" ); document.write( ".
\n" ); document.write( "cross multiply
\n" ); document.write( ".
\n" ); document.write( "8x = 7*180 - 7x
\n" ); document.write( ".
\n" ); document.write( "15x = 1260
\n" ); document.write( ".
\n" ); document.write( "x= 84
\n" ); document.write( ".
\n" ); document.write( "(180-x) = 180-84 = 96
\n" ); document.write( ".
\n" ); document.write( "check,,ratio 84/96 = 7/8,,,,ok
\n" ); document.write( ",,,,,96 - 84 = 180,,,ok
\n" ); document.write( "
\n" );
