Sine Sum Identity From Table Data

Question

The data in the table support which of the following trigonometric identities?

| $$\alpha$$ (°) | $$\beta$$ (°) | $$\sin(\alpha+\beta)$$ (approx.) | $$\sin(\alpha)\cos(\beta)+\cos(\alpha)\sin(\beta)$$ (approx.) |
|----------------|--------------|------------------------------|-----------------------------------------------|
| 30             | 45           | 0.966                        | 0.966                                         |
| 45             | 30           | 0.966                        | 0.966                                         |

Accepted Answer

$$\sin(\alpha+\beta)=\sin(\alpha)*\cos(\beta)+\cos(\alpha)*\sin(\beta)$$

Answer

$$\sin(\alpha+\beta)=\sin(\alpha)+\sin(\beta)$$

Answer

$$\sin(\alpha+\beta)=\cos(\alpha)*\sin(\beta)$$

Answer

$$\sin(\alpha+\beta)=\cos(\alpha)*\cos(\beta)$$
