sin 30°
The value of sin 30° is equal to 0
The value of sin 30° is equal to 0.5.
In trigonometry, the sine is a mathematical function that relates an angle of a right triangle to the ratio of the length of the side opposite the angle to the length of the hypotenuse. In this case, when we say sin 30°, we are referring to the sine of an angle of 30 degrees.
To find the value of sin 30°, we can draw a right triangle with an angle of 30 degrees. Let’s label the sides of the triangle:
– The side opposite the angle (30°) will be labeled as “opposite”.
– The side adjacent to the angle (forming the right angle) will be labeled as “adjacent”.
– The hypotenuse (the longest side) will be labeled as “hypotenuse”.
Now, we need to determine the lengths of the sides of the triangle. In a 30-60-90 triangle, the side lengths have a specific ratio. The ratio is 1:√3:2, where 1 represents the length of the side opposite the 30-degree angle, √3 represents the length of the side opposite the 60-degree angle, and 2 represents the length of the hypotenuse.
In this case, the side opposite the 30-degree angle is 1, and the hypotenuse is 2. So, for sin 30°, we have:
sin 30° = opposite / hypotenuse = 1 / 2 = 0.5
Therefore, the value of sin 30° is 0.5.
