20sin(30degress)

Answer 1

[AI-generated answer — Explain Bot]

To find the value of 20sin(30 degrees), you can use the trigonometric identity that relates the sine function to the unit circle.

The unit circle is a circle with a radius of 1, centered at the origin of a coordinate plane. It is used to determine the values of trigonometric functions for different angles.

In this case, we are looking for the sine of 30 degrees. Since 30 degrees is a commonly known angle, we can recall the exact value of sin(30 degrees) without further calculation. The value of sin(30 degrees) is 1/2.

Now, with the value of sin(30 degrees), we can calculate the expression 20sin(30 degrees) as follows:

20sin(30 degrees) = 20 * (1/2)
= 10

Therefore, the value of 20sin(30 degrees) is 10.
