Let x = one angle, y = second angle. Supplementary angles add to 180, so
\n" ); document.write( "(i) $\"X+%2B+Y+=+180\"$
\n" ); document.write( "From the given, we can say X = Y + 15. So we have
\n" ); document.write( "(ii) $\"Y+%2B+15+%2B+Y+=+180\"$
\n" ); document.write( "solving for y, we get
\n" ); document.write( "(iii) $\"2Y+%2B+15+=+180\"$
\n" ); document.write( "(iv) $\"2Y+=+165\"$
\n" ); document.write( "(vi) $\"Y+=+82.5\"$
\n" ); document.write( "This means that X = 97.5 and Y = 82.5.
\n" ); document.write( "Together they add to 180. \n" ); document.write( "

\n" );
