The measure of 2 supplementary angles are represented by (3x+10)degrees and (7x-40)degrees. Can you help me understand how to determine the measure of each angle?
\n" ); document.write( "-------------
\n" ); document.write( "Supplementary angles add up to 180 degrees
\n" ); document.write( "-------------
\n" ); document.write( "Equation:
\n" ); document.write( "3x+10 + 7x-40 = 180
\n" ); document.write( "10x -30 = 180
\n" ); document.write( "10x = 210
\n" ); document.write( "x = 21
\n" ); document.write( "--------------
\n" ); document.write( "1st angle = 3x+10 = 3*21+10 = 73 degrees
\n" ); document.write( "2nd angle = 7x-40 = 7*21-40 = 147-40 = 107 degrees
