Angle R and angle S are adjacent angles. In any parallelogram, this means they add to 180 degrees\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R+S = 180
\n" ); document.write( "8n + 10n = 180
\n" ); document.write( "18n = 180
\n" ); document.write( "18n/18 = 180/18
\n" ); document.write( "n = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So n = 10. Let's use this to find the numeric value of S
\n" ); document.write( "S = 10n
\n" ); document.write( "S = 10*10
\n" ); document.write( "S = 100
\n" ); document.write( "Angle S is 100 degrees\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "And let's use n = 10 to find R
\n" ); document.write( "R = 8n
\n" ); document.write( "R = 8*10
\n" ); document.write( "R = 80
\n" ); document.write( "Angle R is 80 degrees \n" ); document.write( "
\n" );
