If tanx=114\tan x=\frac{1}{14}tanx=141, the value of tan(x+π4)\tan \left(x+\frac{\pi}{4}\right)tan(x+4π) can be expressed as ab\frac{a}{b}ba, where aaa and bbb are coprime positive integers. What is the value of a+ba+ba+b?
If tanN∘=tan12∘+sec12∘ \tan N ^ \circ = \tan 12 ^ \circ + \sec 12 ^ \circ tanN∘=tan12∘+sec12∘, where 0≤N≤90 0 \leq N \leq 90 0≤N≤90, what is the value of NNN?
