What is the measure of an angle that is twelve less than twice the measure of its supplement?
\n" ); document.write( ":
\n" ); document.write( "Let a = \"an angle\"
\n" ); document.write( "then it's supplement = (180-a)
\n" ); document.write( ":
\n" ); document.write( "Write an equation for what it says
\n" ); document.write( "a = 2(180-a) - 12
\n" ); document.write( "a = 360 - 2a - 12
\n" ); document.write( "a + 2a = 348
\n" ); document.write( "3a = 348
\n" ); document.write( "a = $\"348%2F3\"$
\n" ); document.write( "a = 116 degrees is the angle
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "See it that is true
\n" ); document.write( "116 = 2(180-116) - 12
\n" ); document.write( "116 = 2(64) - 12
\n" ); document.write( "116 = 128 - 12; confirms our solution of a = 116 \n" ); document.write( "

\n" );
