Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 4

In the first option 'raised' is the past(v2) form of the verb 'raise' while the main verb used in the sentence is 'rise' making it inappropriate.
Question : If $\tan3\theta \tan7\theta = 1$, where $7\theta$ is an acute angle, then find the value of $\cot15\theta$.
Option 1: $1$
Option 2: $-1$
Option 3: $-\sqrt{3}$
Option 4: $\sqrt{3}$
Correct Answer: $-1$
Solution : $\tan3\theta \cdot \tan7\theta = 1$ ⇒ $\tan 7\theta = \frac{1}{\tan 3\theta}$ ⇒ $\tan7\theta = \cot3\theta$ ⇒ $\tan7\theta = \tan(90° - 3\theta)$ ⇒ $7\theta + 3\theta = 90°$ ⇒ $10\theta = 90°$ ⇒ $\theta = 9°$ $\therefore$ $\cot15\theta = \cot (15\times 9)°=\cot135° = \cot(90° + 45°)=-\tan45°

Question : If $\sin5\theta = \cos 20° (0°<\theta<90°)$, then the value of $\theta$ is:
Option 1: 4°
Option 2: 22°
Option 3: 10°
Option 4: 14°
Correct Answer: 14°
Solution : Given: $\sin5\theta = \cos 20° (0°<\theta<90°)$ We know, $\cos 20°=\cos(90°-70°)=\sin70°$ So, $\sin5\theta=\sin 70°$ $⇒5\theta=70°$ $\therefore \theta=14°$ Hence, the correct answer is 14°.
