Answer 1

Here is ur answer...

Hope this will help you

Answer 2

$\sin \alpha = \frac{ \sqrt{3} }{4} \: and \: \cos\beta = 0 \\ \sin \alpha = \sin60 \: and \: \cos\beta = \cos90 \\ \alpha = 60 \: and \: \beta = 90 \\ so \: (\beta - \alpha ) = 90 - 60 \\ (\beta - \alpha ) = 30(ans).$

Here is your answer.

HOPE IT IS HELPFUL.☺
