    It's a very commonly known value. Once you have the angle you will have all your answers.

    Hint: I would suggest you memorize what the sine and cosine of 30,45 and 60 degrees is because you'll see them a lot in exercises and tests.

    \[\sin x=\frac{ 1 }{ 2 }\] \[\sin ^2x+\cos ^2x=1,\cos ^2x=\frac{ 3 }{ 4 }\] \[\cos x=\pm \frac{ \sqrt{3} }{ 2 }\] \[\tan x=\pm ?\]

    \[tanx=\frac{ \sin x }{ \cos x }\]

    no \[\pm \frac{ \frac{ 1 }{ 2 } }{ \frac{ \sqrt{3} }{ 2 } }=\pm \frac{ 1 }{ \sqrt{3} }=\pm \frac{ \sqrt{3} }{ 3 } = \pm \frac{ 1.732 }{ 3 }=?\]
