Answer:

$- \frac{5}{6}$

Step-by-step explanation:

The first thing to do is solve for the root. A trick is to ignore the numerator and only focus on the denominator in the root. So it is a third root so you have to find out what multiplied by itself three times is 343. The correct answer for that is 7. So now we must introduce the numerator back, so it would be:

$\frac{1}{7}$

I'll show the new expression below.

$\frac{1}{6} - 7( \frac{1}{7} )$

Second order of business is to multiply the second half of the expression. Easy enough the 7 cancels out the 1/7. New expression below.

$\frac{1}{6} - 1$

Now just solve for that.

$- \frac{5}{6}$

The area of a rhombus can be computed from its side (s) and angle (θ) by
.. A = s^2*sin(θ)
For your numbers, this is
