A 30-60-90 triangle is a right triangle with angles of 30 degrees, 60 degrees, and 90 degrees. It has special properties related to the lengths of its sides, which can make it very helpful when learning trigonometry. The ratios of the side lengths are constant for all 30-60-90 triangles: the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60.

When writing about 30 60 90 triangle, we mean the angles of the triangle, that are equal to 30°, 60° and 90°. Assume that the shorter leg of a 30 60 90 triangle is equal to a. Then: The second leg is equal to a√3; The hypotenuse is 2a; The area is equal to a²√3/2; and The perimeter equals a (3 + √3).

The sine values in degrees oscillate from -1 to +1. The angles between 0° and 90° have positive values starting from 0 and ending at +1. All values of the sine in degrees repeat cyclically. You can calculate them with the following relationships: sin (α + 90°) = sin (90° - α); sin (α + 180°) = -sin (α); and.
How do you find the value of sin 60? Socratic
Step 1: Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot. Step 2: Determine the value of sin To determine the values of sin, divide 0, 1, 2, 3, 4 by 4 under the root, respectively. See the example below.

Trigonometric Table. A trigonometric table is a table that lists the values of the trigonometric functions for various standard angles such as 0°, 30°, 45°, 60°, and 90°. Trigonometric table comprises trigonometric ratios - sine, cosine, tangent, cosecant, secant, cotangent. These ratios, in short, are written as sin, cos, tan, cosec, sec, and cot.

The value of Sin(30) holds significance in the analysis of special triangles like the 30-60-90 triangle and in geometric calculations. This is where Sin(30) comes into play. The value of the sine of the 30-degree angle, mathematically expressed as Sin(30), is equal to 1/2. This means that the short side will be half the length of the hypotenuse.
