\n" ); document.write( "\n" ); document.write( " $\"sin%28A%29=+15%2F17\"$ \r
\n" ); document.write( "\n" ); document.write( "recall that $\"sin%28A%29=+opp%2Fhyp\"$ \r
\n" ); document.write( "\n" ); document.write( "so we know that $\"opp=15\"$ and $\"hyp=17\"$ \r
\n" ); document.write( "\n" ); document.write( "since $\"cos%28+A%29=adj%2Fhyp\"$ , use $\"opp=15\"$ and $\"hyp=17\"$ to calculate $\"adj\"$ side\r
\n" ); document.write( "\n" ); document.write( " $\"adj=sqrt%2817%5E2-15%5E2%29\"$
\n" ); document.write( " $\"adj=sqrt%2864%29\"$
\n" ); document.write( " $\"adj=8\"$ \r
\n" ); document.write( "\n" ); document.write( "i)
\n" ); document.write( "then $\"cos%28+A%29=8%2F17\"$ \r
\n" ); document.write( "\n" ); document.write( "ii)
\n" ); document.write( " $\"tan%28A%29=opp%2Fadj\"$
