B 4.0 cm because if you think about it the one that says 3.3 cm is actually just slightly shorter than w so it has to be 4.0cm

Answer

B) 4.0 cm

Explanation

First, we can adapt the law of sines to the notation of our triangle:

$\frac{sin(W)}{w} =\frac{sin(U)}{u}$

Now, we can infer from our diagram that W=39 , U=31 , and u=3.3 , so we can replace the values in our previous expression:

$\frac{sin(W)}{w} =\frac{sin(U)}{u}$

$\frac{sin(39)}{w} =\frac{sin(31)}{3.3}$

Finally, we can solve for :

$\frac{3.3sin(39)}{w} =sin(31)$

3.3sin(39)=wsin(31)

$\frac{3.3sin(39)}{sin(31)} =w$

$w=\frac{3.3sin(39)}{sin(31)}$

w=4.03224

Which rounds to w=4.0

We can conclude that the best approximation of w is 4.0 cm

Fifth Degree Polynomials

One to five roots.

Zero to four extrema.

One to three inflection points.

No general symmetry.

It takes six points or six pieces of information to describe a quintic function.

Roots are not solvable by radicals (a fact established by Abel in 1820 and expanded upon by Galois in 1832)
