The answer is b this is because you add the angles
Use the 30-60-90 triangle.
Tan is opposite over adjacent.
![\frac{1}{ \sqrt{3} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%5Csqrt%7B3%7D%20%7D%20)
Square roots cannot be on the bottom.
![\frac{1}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%5Csqrt%7B3%7D%20%7D%20%20%5Ctimes%20%20%5Cfrac%7B%20%5Csqrt%7B3%7D%20%7D%7B%20%5Csqrt%7B3%7D%20%7D%20)
The bottom cancel out the square root bar.
Your answer is:
![\frac{ \sqrt{3} }{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%7B3%7D%20%7D%7B3%7D%20)
(It's best to memorize the 30-60-90 and the 45-45-90 triangles during trigonometry. It helps a lot.)
Hope this helps!
