QuestionFind the missing coordinate $x$ for the point $\left(x, \frac{2}{3}\right)$ on the unit circle in quadrant II.

Studdy Solution
Since the point is in quadrant II, the x-coordinate should be negative. Therefore, the missing coordinate is $x = -\frac{\sqrt{5}}{3}$.
The missing coordinate is $x = -\frac{\sqrt{5}}{3}$.
