How to find a number using Pythagoras Theorem using C#?

Firstly, set the first two numbers −

double val1, val2;
val1 = 10;
val2 = 5;

Now use the Math.Sqrt function to use Pythagoras Theorem.

res = Math.Sqrt(val1 * val1 + val2 * val2);

Example

 Live Demo

using System;
public class Program {
   public static void Main(string[] args) {
      double val1, val2, res;
      val1 = 10;
      val2 = 5;
      res = Math.Sqrt(val1 * val1 + val2 * val2);

      Console.WriteLine("Result = {0}", res);
      Console.ReadLine();
   }
}

Output

Result = 11.1803398874989
