Sine and Cosine Function Values Practice Test

The point $$P(-\frac{5\sqrt{2}}{2}, \frac{5\sqrt{2}}{2})$$ is on a circle of radius 5 centered at the origin. Which of the following could be the angle $$\theta$$ in standard position corresponding to point $$P$$?

A point $$P(x,y)$$ on a circle of radius 8 corresponds to an angle $$\theta$$ in standard position. If $$\sin\theta = \frac{3}{4}$$ and the terminal ray of $$\theta$$ is in Quadrant II, what are the coordinates of point $$P$$?
