Question : If $4-2 \sin ^2 \theta-5 \cos \theta=0,0^{\circ}<\theta<90^{\circ}$, then the value of $\cos \theta+\tan \theta$ is:
Option 1: $\frac{2-\sqrt{3}}{2}$
Option 2: $\frac{1+2 \sqrt{3}}{2}$
Option 3: $\frac{2+\sqrt{3}}{2}$
Option 4: $\frac{1-2 \sqrt{3}}{2}$
Correct Answer: $\frac{1+2 \sqrt{3}}{2}$
Solution : Given: $4-2 \sin ^2 \theta-5 \cos \theta=0$ ⇒ $4-2(1- \cos ^2 \theta)-5 \cos \theta=0$ ⇒ $4-2+ 2\cos ^2 \theta-5 \cos \theta=0$ ⇒ $2\cos ^2 \theta-5 \cos \theta+2=0$ ⇒ $2\cos ^2 \theta-4 \cos \theta- \cos \theta+2=0$ ⇒ $2\cos \theta(\cos \theta-2) - 1(\cos \theta-2) = 0$
