Answer:

1) The angle would be 150 degrees

a) coordinates would be ( $-\frac{\sqrt{3}}{2}$ , $\frac{1}{2}$ )

b) Trigonometric ratios:

sin: $\frac{1}{2}$

cos: $-\frac{\sqrt{3}}{2}$

tan: $-\frac{\sqrt{3}}{3}$

csc: 2,

sec: $-\frac{2\sqrt{3}}{3}$

cot: $\sqrt{3}$

Explanation:

$\frac{17\pi }{6}$ simplifys to $\frac{5\pi }{6}$ which has a reference angle of $\frac{\pi }{6}$ . We can take the coordinates of $\frac{\pi }{6}$ and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
