6-9.

Nossis has been working on his geometry homework and he is almost finished. His last task is to find a solution of $\text{sin}\left(x\right) = 0.75$. Nossis cannot figure out what x could be! Explain how he can find a value for x and show that it works.

The inverse of $\text{sin}\left(x\right)$ is $\text{sin}^{−1}\left(x\right)$.
