Create a Formula for the Width of the Armhole Cuffs

How to calculate the width of the armhole cuffs:

The width of the armhole cuffs are calculated doubling the sum of length of the following armhole segments:

[Width of the Armhole Cuff] = 2*(x+y)

• Calculation of x:
  x is calculated according to the theorem of Pythagoras.
  
  x² = a²+b²
  x = √(a²+b²)

a = ([Body Width at the Waistband]-[Shoulder Width])/2
b = [Height of the Armhole Narrowing]
x = √((([Body Width at the Waistband]-[Shoulder Width])/2)²+[Height of the Armhole Narrowing]²)

• Calculation of y
  
  y = [Armhole Drop]–[Height of the Armhole Narrowing]

Formula for the width of the armhole cuffs:

The final formula for the width of the armhole cuffs results replacing the calculation of x and y in the original formula.
[Width of the armhole cuffs] = 2*(√((([Body Width at the Waistband]-[Shoulder Width])/2)²+[Height of the Armhole Narrowing]²)+[Armhole Drop]–[Height of the Armhole Narrowing])
