A) \[30{}^\circ \]
B) \[45{}^\circ \]
C) \[60{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: A
Solution :
| [a] We have, \[2\sin \,\,2\theta =\sqrt{3}\] |
| \[\Rightarrow \,\,\,\,\sin 2\theta =\frac{\sqrt{3}}{2}\,\,\,\,\,\Rightarrow \,\,\,2\theta =60{}^\circ \]\[\left[ \sin 60{}^\circ =\frac{\sqrt{3}}{2} \right]\] |
| \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\theta =\frac{60{}^\circ }{2}=30{}^\circ \] |
