Law of Sines: Angle A is equal to [imath]\pi - \alpha - \theta[/imath] and
[imath]\dfrac{sin(\theta)}{1} = \dfrac{sin(A)}{2}[/imath]

Let C be the centre point. Use the cos rule to find an expression for side c in terms of \(\displaystyle \alpha\).
Use the sine rule and then the cosine rule to find expressions for sin\(\displaystyle \theta\) and cos\(\displaystyle \theta\) in terms of \(\displaystyle \alpha\).
Combine to find an expression for tan\(\displaystyle \theta\) in terms of \(\displaystyle \alpha\).

I got an expression for tan\(\displaystyle (\theta)\) in terms of \(\displaystyle \alpha\) as in the hint.

Stopped to do what? - sing a song?
Every alternate "ban him" should be bold letters - just so that emphasis on ban is not lost...............
