How do you find the value of sin 30 degrees?
The value of sin 30 degrees can be calculated by constructing an angle of 30° with the x-axis, and then finding the coordinates of the corresponding point (0.866, 0.5) on the unit circle. The value of sin 30° is equal to the y-coordinate (0.5). ∴ sin 30° = 0.5.

What is the exact value of sin 30 enter your answer as a simplified fraction in the box $$?
Identify the angle, the adjacent side, the side opposite the angle, and the hypotenuse of the right triangle. Find the required function: sine as the ratio of the opposite side to the hypotenuse. cosine as the ratio of the adjacent side to the hypotenuse.
How do you find the value of sin degrees?
To find the value of sin 30 degree, we will use the following formula, Sinϴ = Perpendicular Hypotenuse. Thus, the value of Sin 30 degree is equal to 12(half) or 0.5. Just like the way we derived the value of sin 30 degrees, we can derive the value of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°.
