Two angles are supplementary. Find their measures if one of them is 20 less than three times the measure of the other.
\n" ); document.write( ".
\n" ); document.write( "Let x = one angle
\n" ); document.write( "then
\n" ); document.write( "180-x = second angle (supplement)
\n" ); document.write( ".
\n" ); document.write( "180-x = 3x-20
\n" ); document.write( "180 = 4x-20
\n" ); document.write( "160 = 4x
\n" ); document.write( "40 degrees = x
\n" ); document.write( ".
\n" ); document.write( "second angle:
\n" ); document.write( "180 - x = 180-40 = 140 degrees
\n" ); document.write( ".
\n" ); document.write( "answer: 40 and 140 degrees \n" ); document.write( "
\n" );
