Hello,\r
\n" ); document.write( "\n" ); document.write( "Supplementary angles means that the sum of the two angles is 180.
\n" ); document.write( "Angle 'A' is 81.2. It asked for a supplement. Since the other angle is unknown, you take 180 and subtract it from 81.2 and you get 98.8 \r
\n" ); document.write( "\n" ); document.write( "180 - 81.2 = 98.8\r
\n" ); document.write( "\n" ); document.write( "The supplement of angle 'A' is 98.8
\n" ); document.write( "You check by adding the 2 angles and if you get 180, it's right!
\n" ); document.write( "I hope this helps!
