30 degrees
explanation
2Cosx-radical 3=0
Then 2cosx=radical 3
and cos x=(radical 3)/2
Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle.
So the answer is 30 degrees.

What is Exact value?
Exact value means you do not approximate. So if you answer has a radical in it, you leave the radical and do not approximate it. If it has a fraction such as 1/3, you leave it and do not approximate it as .3 or .33 or even.333333333333333...

What is the exact radians measure of 623 degrees?
360 degrees equals 2(pi) radians. Therefore, [2(pi)](623/360) = (623/180)(pi). Since I have not discovered any common integral factor for 623 and 180, I believe this is the simplest manner in which the exact radians measure can be written.
