We will solve using the law of sines as follows:

Now, we solve for X:
![\Rightarrow X=\frac{\sin(60)}{\sin(30)}\Rightarrow X=\sqrt[]{3}](https://tex.z-dn.net/?f=%5CRightarrow%20X%3D%5Cfrac%7B%5Csin%2860%29%7D%7B%5Csin%2830%29%7D%5CRightarrow%20X%3D%5Csqrt%5B%5D%7B3%7D)
So, the length of X is sqrt(3).
I think you mean circumference...Area is

. We have the area so we need to use it to solve for the radius which we will then use in the circumference formula.

. Divide both sides by pi to get

. Of course the simplification of the left side gives us

and r = 4. Now fill that in to the circumference formula, which is

, to get C

which is a circumference of
