Question : If $3+\cos ^2 \theta=3\left(\cot ^2 \theta+\sin ^2 \theta\right), 0^{\circ}<\theta<90^{\circ}$, then what is the value of $(\cos \theta+2 \sin \theta)$ ?
Option 1: $\frac{2 \sqrt{3}+1}{2}$
Option 2: $3 \sqrt{2}$
Option 3: $\frac{3 \sqrt{3}+1}{2}$
Option 4: $\frac{\sqrt{3}+2}{2}$
Correct Answer: $\frac{2 \sqrt{3}+1}{2}$
Solution : According to the question $3+\cos ^2 \theta=3\left(\cot ^2 \theta+\sin ^2 \theta\right), 0^{\circ}<\theta<90^{\circ}$, ⇒ $3 + \cos^{2}\theta$ = 3($\cot^{2}\theta + \sin^{2}\theta$) ⇒ $3 + \cos^{2}\theta$ = 3 $\cot^{2}\theta + 3(1 - \cos^{2}\theta$) ⇒ $3 + \cos^{2}\theta$ = 3 $\cot^{2}\theta + 3 - 3\cos^{2}\theta$ ⇒ $4
