Program:

The source code to demonstrate the trigonometry angles in degrees is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to demonstrate the Trigonometry Angles 
//in degrees using Math class

using System;

class Demo
{
    static void Main(string[] args)
    {
        double sin60;
        double cos60;
        double tan60;

        sin60 = Math.Sin(60 * Math.PI / 180);
        cos60 = Math.Cos(60 * Math.PI / 180);
        tan60 = Math.Tan(60 * Math.PI / 180);

        Console.WriteLine("Sin (60)     = "+ sin60);
        Console.WriteLine("Cos (60)     = "+ cos60);
        Console.WriteLine("Tan (60)     = "+ tan60);
    }
}

Output:

Sin (60)     = 0.866025403784439
Cos (60)     = 0.5
Tan (60)     = 1.73205080756888

Explanation:

Here, we created a Demo class that contains the Main() method. In the Main() method, we created three variables of double type.

sin60 = Math.Sin(60 * Math.PI / 180);
cos60 = Math.Cos(60 * Math.PI / 180);
tan60 = Math.Tan(60 * Math.PI / 180);

In the above code we calculated the trigonometry angles based on specified degrees using predefined method of Math class, and then print the result on the console screen.
