Step-by-step explanation:
Answer: 30° and 330°
<u>Step-by-step explanation:</u>
sec θ = ![\frac{2\sqrt{3}}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Csqrt%7B3%7D%7D%7B3%7D)
sec θ = ![\frac{1}{cos(\theta)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bcos%28%5Ctheta%29%7D)
= ![\frac{2\sqrt{3}}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Csqrt%7B3%7D%7D%7B3%7D)
cos θ = ![\frac{3}{2\sqrt{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%5Csqrt%7B3%7D%7D)
cos θ = ![\frac{3}{2\sqrt{3}}(\frac{\sqrt{3}}{\sqrt{3}})](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%5Csqrt%7B3%7D%7D%28%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B%5Csqrt%7B3%7D%7D%29)
cos θ = ![\frac{3\sqrt{3}}{3*2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7B3%7D%7D%7B3%2A2%7D)
cos θ = ![\frac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
Look at the Unit Circle to see that cos =
at 30° and 330° ( which is equivalent to π/6 and 11π/6)
