CPM Homework Help : CCA2 Problem 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.

Hint:

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 $.75$ .
