\n" ); document.write( "---------------------------------------------------------------------
\n" ); document.write( "In triangle LMN, L = 27.0 cm, m = 31.4 cm, and angle measure at N = 82°.
\n" ); document.write( "Determine the measure of n to the nearest tenth of a centimetre.
\n" ); document.write( "-----------------------------------------------------------------------
\n" ); document.write( "That means the interior angle between segments MN and LN is 82 degrees.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The question is asking for the length of segment LM.\r
