Question : $\frac{\cos 20^{\circ}}{\sin 70^{\circ}}+\frac{\cos \theta}{\sin \left(90^{\circ}-\theta\right)}=$_________,

Option 1: $-2$

Option 2: $\frac{1}{2}$

Option 3: $-\frac{1}{2}$

Option 4: $2$

Team Careers360 16th Jan, 2024

Correct Answer: $2$


Solution : We know that $\text{sin}(90^{\circ} - \theta)= \cos \theta$
$\frac{\cos 20^{\circ}}{\sin 70^{\circ}}+\frac{\cos \theta}{\sin \left(90^{\circ}-\theta\right)}$
= $\frac{\cos 20^{\circ}}{\sin (90^{\circ}-20^{\circ})}+\frac{\cos \theta}{\cos \theta}$
= $\frac{\cos 20^{\circ}}{\cos (20^{\circ})}+\frac{\cos \theta}{\cos \theta}$
= 1 + 1
= 2
Hence, the correct answer is $2$.
