Answer 1

$\sqrt{ \frac{1 + \sin30 }{2} } \\ \\ = \sqrt{ \frac{1 + \frac{1}{2} }{2} } \\ \\ = \sqrt{ \frac{ \frac{3}{2} }{2} } \\ \\ = \sqrt{ \frac{3}{4} } \\ \\ = \frac{ \sqrt{3} }{2}$

The answer will be ------- √3/2

It doesn't match with your options. But it's correct I think so. May be the options are mistaken in your book .

Hope it will help you .
