Two angles are supplementary when their sum is 180 degrees, so...
\n" ); document.write( "1) \"PQR%2BABC+=+180\"
\n" ); document.write( "The problem states that:
\n" ); document.write( "2) \"PQR+=+3%28ABC%29\" Substitute this into equation 1) for angle \"PQR\".
\n" ); document.write( "1a) \"3%28ABC%29%2BABC+=+180\" Simplify.
\n" ); document.write( "1b) \"4%28ABC%29+=+180\" Divide both sides by 4.
\n" ); document.write( "1c) \"highlight%28ABC+=+45%29%29\"degrees and...
\n" ); document.write( "\"PQR+=+3%28ABC%29\"
\n" ); document.write( "\"PQR+=+3%2845%29\"
\n" ); document.write( "\"highlight%28PQR+=+135%29\"degrees.\r
