Question

Someone please let me know the answer ​

Answer 1

The answer is 30°

Explanation:

`when \: \: √(3) \sin( \alpha ) - \cos( \alpha ) = 0 \\ √(3) \sin( \alpha ) = \cos( \alpha ) \\ multiply \: by \: (1)/( √(3) \cos( \alpha ) ) \\ then \\ ( \sin( \alpha ) )/( \cos( \alpha ) ) = (1)/( √(3) ) \\ \tan( \alpha ) = (1)/( √(3) ) \\ then \: \alpha = 30`
