\n" ); document.write( "the sum of all three angles is \"A%2BB%2BC=180\"\r
\n" ); document.write( "\n" ); document.write( "if \"A+=+61\"° and \"B+=+66\"°, then\r
\n" ); document.write( "\n" ); document.write( "\"61%2B66%2BC=180\"\r
\n" ); document.write( "\n" ); document.write( "\"127%2BC=180\"\r
\n" ); document.write( "\n" ); document.write( "\"C=180-127\"\r
\n" ); document.write( "\n" ); document.write( "\"C=53\"°
