Answer 1

$\huge\color{blue}\underline{\underline{Answer }}:$

(a)First quadrant

$\huge\color{blue}\underline{\underline{Solution }}:$

$\sf • sin \theta \frac{√3}{2} \\ => \theta = 45° \\ \\ \\ • \sf Cos\theta= -\frac{1}{2} \\ \ \ \ \ \ \ \ \theta=60° \ \ \ \ \ \ \ \sf \color{brown}(Cos\ always \ absorb \ -ive)$

Hence, θ lies in First quadrant .
