Good luck and have fun, remember ‘ing in your english you often forget. When you are doing something, ‘ing should be added to the end of the action, playing rolling flying. 🙂
Calcul of A’C’
If the angle B’ is right, I calcul A’C’ with the Pythagoras’ theorem :
A’C’ ² = A’B’ ² + B’C’ ²
A’C’ ² = 3.1² + 5.9 ²
A’C’ ² = 9.61 + 34.81
A’C’ = Racine² of 44.42
A’C’ = about 6.66
So????
