What is the sine of a 30-degree angle, and how can I use it to find the length of the opposite side in a right triangle?

The sine of a 30-degree angle is 0.5. In a right triangle, if you know the hypotenuse length, you can find the length of the opposite side by multiplying the hypotenuse by the sine of the angle. For example, if the hypotenuse is 10 units, the opposite side would be 10 * 0.5 = 5 units.
