Answer: ![-\dfrac{1}{2}](https://tex.z-dn.net/?f=-%5Cdfrac%7B1%7D%7B2%7D)
<u>Step-by-step explanation:</u>
The coordinate at -30° <em>(-30° = 330°)</em> = ![\bigg(\dfrac{\sqrt3}{2},-\dfrac{1}{2}\bigg)\\](https://tex.z-dn.net/?f=%5Cbigg%28%5Cdfrac%7B%5Csqrt3%7D%7B2%7D%2C-%5Cdfrac%7B1%7D%7B2%7D%5Cbigg%29%5C%5C)
the x-value is ![\dfrac{\sqrt3}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csqrt3%7D%7B2%7D)
the y-value is
