5-10.

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

x is an angle. Using a calculator, be sure your calculator is in degree mode, then type: $\sin^{-1}(.75)$. Your answer should be an angle in degrees. Check your work by finding the sine of your answer. It should be $.75$.
