Let A and B be the two angles that are supplementary.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let A = 4x-10
\n" ); document.write( "Let B = 5x+1\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A+B = 180
\n" ); document.write( "(4x-10)+(5x+1) = 180
\n" ); document.write( "9x-9 = 180
\n" ); document.write( "9(x-9) = 180
\n" ); document.write( "x-9 = 180/9
\n" ); document.write( "x-9 = 20
\n" ); document.write( "x = 20+9
\n" ); document.write( "x = 29\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The value of x is x = 29
\n" ); document.write( "
\n" ); document.write( "
\n" );
