\n" ); document.write( "Let the third angle be x degrees\r
\n" ); document.write( "\n" ); document.write( "42+103+x =180
\n" ); document.write( "145+x=180
\n" ); document.write( "x=180-145
\n" ); document.write( "x=35\r
\n" ); document.write( "\n" ); document.write( "The third angle is 35 degrees.\r
