+tan%28%2817%2F12%29%2Api+%29+
Note that +%2812%2F12%29%2Api+=+pi+
so, +%2817%2F12%29%2Api+=+pi+%2B+%285%2F12%29%2Api+
-----------
This is an angle in the 3rd quadrant
where the tangent is (-)/(-), which
is positive.
-----------
+pi%2F3+=+60+ degrees
+pi%2F6+=+30+ degrees
+pi%2F12+=+15+ degrees
+%285%2F12%29%2Api+=+75+ degrees
-----------
+tan%28+%2817%2F12%29%2Api%29+=+tan%28+%285%2F12%29%2Api%29+ answer
