Calculate \(\arccos \sqrt{\cfrac{1+\sqrt{\cfrac{1-\sqrt{\cfrac{1-\sqrt{\cfrac{1+\cfrac{\sqrt{3}}{2}}{2}}}{2}}}{2}}}{2}}\).

I'm not exactly sure how to approach this, but I have this as progress: \(\arccos \sqrt{\frac{1+\frac{\sqrt{3}}{2}}{2}} = \frac{\frac{\pi} {6}} {2}\). I don't know how to deal with it further, could someone help me?
