if possible please mark as brainliest and see the image for explaination

Answer 2

Answer:

$\sin4 \theta = \frac{ \sqrt{3} }{2}$

We know that

$\sin60° = \frac{ \sqrt{3} }{2}$

So

$\sin4 \theta = \sin60° \\ \\ \cancel{\sin} \: 4 \theta = \cancel { \sin} \: 60° \\ \\ 4 \theta = 60 \\ \\ \theta = \frac{60}{4} \\ \\ \large \boxed{ \bf \green{ \theta = 15°}}$
