As per Trig angles rule , It is the All Sine Tan Cos
that means ..All angles will be positive in first Quadrant
Sin will be positive in second quadrant
Cosine will be positive in fourth Quadrant
Tangent will be positive in 3rd Quadrant .
so here in the problem,
cosθ < 0 and tan θ > 0 , where θ is located..
from above 4 conditions , Cosine is negative and tangent will be positive in 3rd Quadrant
so Answer is θ is located in Third Quadrant
