D.\r \n" ); document.write( "\n" ); document.write( "tan = opposite/adjacent \n" ); document.write( "cot = adjecent/opposite But in this problem we switched which vertex we were making that statement about. \r \n" ); document.write( "\n" ); document.write( "Draw the tirangle, label sides a and b and then put the angles A and B at the vertex opposite the side. Then see how what we said above implies the same ratio \n" ); document.write( " |
