Answer 2

$\sin75 = \sin(45 + 30) \\ \\ = \sin45. \cos30 + \cos45. \sin30 \\ \\ = \frac{1}{ \sqrt{2} } \times \frac{ \sqrt{3} }{2} + \frac{1}{ \sqrt{2} } \times \frac{1}{2} \\ \\ = \frac{ \sqrt{3} }{2 \sqrt{2} } + \frac{1}{2 \sqrt{2} } \\ \\ = \frac{ \sqrt{3 } + 1}{2 \sqrt{2} }$

I hope this helps.
