I'm assuming this is a triangle.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If so, then let x be the third missing angle. All 3 angles of any triangle always add to 180 degrees (something to memorize). So,\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "63 + 26 + x = 180\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "89 + x = 180\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 180 - 89\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 91\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, the third missing angle is 91 degrees.
\n" ); document.write( "
\n" );
