Two angles are supplementary.
\n" ); document.write( "A + B = 180
\n" ); document.write( " The measure of one is four-fifths the measure of the other.
\n" ); document.write( "B = .8A
\n" ); document.write( "therefore
\n" ); document.write( "A + .8A = 180
\n" ); document.write( "1.8A = 180
\n" ); document.write( "A = 180/1.8
\n" ); document.write( "A = 100 degrees
\n" ); document.write( ":
\n" ); document.write( " Find the measure of each angle. I'll let you find B
\n" ); document.write( "
\n" );
