Unit Circle Coordinates From a Table

Question

According to the table above, what are the coordinates on the unit circle corresponding to a 45° angle?

| Angle (°) | Radians                | Coordinates                                                       |
|-----------|------------------------|-------------------------------------------------------------------|
| 45        | $$\frac{\pi}{4}$$      | $$\left(\frac{\sqrt{2}}{2},\frac{\sqrt{2}}{2}\right)$$           |
| 30        | $$\frac{\pi}{6}$$      | $$\left(\frac{\sqrt{3}}{2},\frac{1}{2}\right)$$                   |
| 60        | $$\frac{\pi}{3}$$      | $$\left(\frac{1}{2},\frac{\sqrt{3}}{2}\right)$$                   |
