Answer:

x =3 sqrt(3)

Step-by-step explanation:

cos theta = adj/ hyp

cos 60 = x/ 6 sqrt(3)

Multiply each side by 6 sqrt(3)

6 sqrt(3) cos 60 = x/6 sqrt(3)/ 6 sqrt(3)

x =cos 60 * 6 sqrt(3)

x =3 sqrt(3)

<h3>Answer: Choice E</h3>

Work Shown:

$c^2 = a^2 + b^2 - 2ab\cos(C)\\\\c^2 + 2ab\cos(C) = a^2 + b^2\\\\2ab\cos(C) = a^2 + b^2 - c^2\\\\\boldsymbol{\cos(C) = \frac{a^2 + b^2 - c^2}{2ab}}\\\\$
