If equation x2tan⁡2θ−(2tan⁡θ)x+1=0x^2 \tan^2 \theta - (2 \tan \theta)x + 1 = 0 and (11+log⁡bac)x2+(11+log⁡cab)x+(11+log⁡abc−1)=0\left( \frac{1}{1 + \log_b ac} \right) x^2 + \left( \frac{1}{1 + \log_c ab} \right) x + \left( \frac{1}{1 + \log_a bc} - 1 \right) = 0 (where a,b,c>1a, b, c > 1 ) have a common root and then 2nd equation has equal roots, then number of possible value of θ\theta in (0,π)(0, \pi) is
