What is the sine of a 30-degree angle?
Answer 1
Richard Fisher
The sine of a 30-degree angle is 0.5. This is derived from the properties of a 30-60-90 right triangle, where the ratio of the length of the side opposite the 30-degree angle to the hypotenuse is 1:2, resulting in a sine value of 1/2 or 0.5.
