# Using the Law of Cosines in a Multiple Triangle Figure

In the figure, triangle ABC is a right triangle, CQ = 4, and BQ = 8. Also, ∠AQC = 30º and ∠CQB = 45º. Find the length of AQ. [Hint: first use the Law of Cosines to find expressions for a2, b2, and c2.]

Essentially what the question is asking is solve, algebraically for x, but I am completely stumped on how to do so.

Any help would be greatly appreciated.
