Yo sup??
To solve this problem u just need the basics of trigonometry
So
Sinx=opposite side/hypotenuse
Cosx=adjacent side/hypotenuse
Tanx=sinx/cosx=opposite/adjacent
Now just plug in the values
Sinx=2√3/4
=√3/2
Cosx=2/4
=1/2
Tanx=√3
If u had a better knowledge of trigonometry then u will find that x is 60° or π/3
Hope this helps
