Answer:

\frac{5}{9}

Step-by-step explanation:

One way to look at it is to have 6 \frac{9}{9} (which is the same as 7) instead. So, you would do this: 6 \frac{9}{9} - 6 \frac{4}{9} = ? Since we know that 6-6 is 0, we don't have to worry about that part. \frac{9}{9} - \frac{4}{9} = \frac{5}{9}

We have that
<span>sin x=2/9

we know that
sin</span>² x+cos² x=1---------> cos² x=1-sin² x-----> cos² x=1-(2/9)²
cos² x=1-(4/81)------> (81-4)/81-----> 77/81
cos x=√(77/81)

Sin 2x = 2 sin x cos x-------> 2*(2/9)*(√(77/81))----> (4/81)*√77---> 0.43

Sin 2x=0.43
so
cos² 2x=1-sin² 2x---------> 1-[0.43]²-----> 1-[0.1878]----> 0.81
cos² 2x=0.81-----------> cos 2x=0.9

tan 2x=sin 2x/cos 2x--------> tan 2x=0.43/0.9---------> tan 2x=0.48

the answers are
sin 2x=0.43
cos 2x=0.9
tan 2x=0.48
