You're given an angle, the side adjacent to the angle, and are looking for the hypotenuse.

Use cosine = adjacent / hypotenuse.

cos(60) = 2√(3) / x

Rearrange the equation to solve for x (multiply both sides by x, then divide both sides by cos(60)).

x = (2√(3)) / (cos(60))

x equates to about 6.928
