x + 2x = 180
\n" ); document.write( "3x = 180
\n" ); document.write( "x = 60 degrees, one angle.
\n" ); document.write( "2x = 120 degrees, the second angle.
\n" ); document.write( "This does check.
\n" ); document.write( "There are two angles in the relationship.
\n" ); document.write( "We can use algebra by making one angle x and the second angle, the supplement, 2x.
\n" ); document.write( "=================================================================================
\n" ); document.write( "For the last part,
\n" ); document.write( "x + x + 20 = 90.
\n" ); document.write( "2x + 20 = 90
\n" ); document.write( "2x = 70
\n" ); document.write( "x = 35
\n" ); document.write( "x = 35 degrees, this is one angle.
\n" ); document.write( "35 + 20 = 55 degrees, this is the second angle.
\n" ); document.write( "35 degrees + 55 degrees = 90 degrees, this does check.
