First off it's Q2 then $\"cos%28theta%29%3C0\"$ ,
\n" ); document.write( "So then,
\n" ); document.write( " $\"sin%5E2%28theta%29%2Bcos%5E2%28theta%29=1\"$
\n" ); document.write( " $\"sin%5E2%28theta%29%2B%28-5%2F13%29%5E2=1%7D%7D%0D%0A%7B%7B%7Bsin%5E2%28theta%29=1-25%2F169\"$
\n" ); document.write( " $\"sin%5E2%28theta%29=144%2F169\"$
\n" ); document.write( " $\"sin%28theta%29=0+%2B-+12%2F13\"$
\n" ); document.write( "Since it's Q2, $\"sin%28theta%29%3E0\"$
\n" ); document.write( " $\"highlight%28sin%28theta%29=12%2F13%29\"$
\n" ); document.write( "and
\n" ); document.write( " $\"tan%28theta%29=%2812%2F13%29%2F%28-5%2F13%29\"$
\n" ); document.write( " $\"highlight%28tan%28theta%29=-12%2F5%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
