Problem 105 of 7
Rearrange trigonometric geometry formula to isolate side or angle: c/sin(C)=d/sin(D) isolate D.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Isolate the trig function or side term.
2. Divide by coefficients as needed.
3. Apply inverse trig for angles and state domain limits.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Inverse trig on a value outside [-1,1] without noting invalidity.
