Algebra.Com's Answer #153685 by RAY100(1637) ![]() You can put this solution on YOUR website! 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( " |
