\n" ); document.write( "You don't solve each triangle, you solve for the sides. Right?\r
\n" ); document.write( "\n" ); document.write( "Angle A = \"90-54+=+36\"°\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Side b:
\n" ); document.write( "\"tan%28B%29=b%2Fa\"

\n" ); document.write( "\n" ); document.write( "side c:
\n" ); document.write( "\"cos%28B%29=a%2Fc\"
\n" ); document.write( "We use the reciprocal trig function of cosine (secant) to make the computation of the fraction easier:
