Find the exact value for Cos θ given that Sin θ= 5/7
\n" ); document.write( "you are given:
\n" ); document.write( "opposite side=5
\n" ); document.write( "hypotenuse=7
\n" ); document.write( "By pythagorean theorem, adjacent side=√(7^2-5^2)=√(49-25)=√24
\n" ); document.write( "cos θ=√24/7
\n" ); document.write( "
\n" );
