Let the angle be A, then its complement is (90-A), so...
\n" ); document.write( "\"A+=+%281%2F2%29%2890-A%29\" Simplify. Multiply by 2.
\n" ); document.write( "\"2A+=+90-A\" Add A to both sides.
\n" ); document.write( "\"3A+=+90\" Divide by 3.
\n" ); document.write( "\"A+=+30\"degrees.
\n" ); document.write( "
\n" );
