Full solution stays hidden until you ask for it.
1. Substitute the input value into the model.
2. Evaluate the trig function at the resulting angle.
3. Interpret the predicted output.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using degrees in a radian model unless converted.
