You don't really need to use complex numbers to solve it. You basically just use the sum/difference formula and the identities like [unparseable or potentially dangerous latex formula], [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula] multiple times.
But the method of using complex numbers is pretty interesting nonetheless.
And anyway, the 89 doesn't usually simplify things that easily. It works from time to time, but you are better off simplifying equations by hand.
Now I know the stakes, and I'm willing to show what I gots. I will see you all at state for the first and final time, so let's end the year with a bang! :)
