This is a stupid question, but it's really important for me and I'm stuck. I hope there's not an anti-math rule in this community.

So it's really simple trig, aka the antichrist, if you ask me. (I'm no good at math.)

Exact answers in simplified radical form:

21cos30=2x
what is x?

Is there a way to find x in simplified radical form?
