To find the value of \(\sin 50^\circ\) rounded to the nearest ten-thousandth, you can use a scientific calculator or a reliable trigonometric table.
Using a scientific calculator:
1. Enter the angle \(50^\circ\).
2. Press the \(\sin\) function key.
The calculator should provide the value of \(\sin 50^\circ\).
The correct value is:
\[
\sin 50^\circ \approx 0.7660
\]
So, the value of \(\sin 50^\circ\) rounded to the nearest ten-thousandth is \(0.7660\).
Thus, the correct option is:
\[\boxed{0.7660}\]
