As I said, I will not solve the puzzle completely, but only mention that for a triangle with two perpendicular sides of 10 degrees each, the error in the hypothenuse is slightly less than 2'.2. This is another example which shows that Mercator maps covering a part of the globe of reasonable size are perfect for navigation.
And for all other purposes :-)
