Can you hint where is my error? The editor says i need to have a return type

I already assign the result to a type double, did i miss something here?

RightTriangle.cs 
namespace Treehouse.CodeChallenges
{
    class RightTriangle
    {
        public static CalculateHypotenuse(double Height, double V)
        {
            Height=5.0;
            V=20.0;

            double res = Height / Math.Sin(V);
            return res;
        }
    }
}

Travis, here's a suggestion:

using System;

namespace Treehouse.CodeChallenges
{
    class RightTriangle
    {
        public static double CalculateHypotenuse(double a, double b) 
        {
            return Math.Sqrt(a * a + b * b);            
        }
    }
}

In your code, you did not add the using directive or the return type (double). The using directive is needed if you are to use the Math class without its associated namespace; otherwise, you need to add System to Math (System.Math). The return type (double) is what the CalculateHypotenuse method should return, so add it before CalculateHypotenuse.

Moreover, Pythagoras' Theorem is a2 + b2 = c2. Use a and b as parameters (to save on typing).

That said, you don't have to store the value in a variable, if you want to further save on typing.

I hope this helps! If you have any further questions, feel free to reach out.
