To find the difference of given expression:

5\frac{2}{3} -3\frac{1}{5}

First step is to subtract the whole number5 and 3.

So, 5 - 3 = 2.

Now we can find the difference of fractions.

To subtract the fractions , we need to find the common denominator.

Common denominator of 3 and 5 is 15.

So, we need to make both the denominator equal to 15.

\frac{2}{3} =\frac{2*5}{3*5} =\frac{10}{15}

Similarly, \frac{1}{5} =\frac{1*3}{3*5} = \frac{3}{15}

Therefore, \frac{2}{3} -\frac{1}{5} =\frac{10}{15} -\frac{3}{15}

=\frac{10-3}{15}

= \frac{7}{15}

So, the difference of given expression is 2\frac{7}{15}.

So, the correct choice is C.

Answer:

x = 16.6

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan 71 = x /5.7

5.7 tan 71 = x

x=16.55400

Rounding to the nearest tenth

x = 16.6
