The third side must be less than the sum of the other two sides and greater than the difference of the other two sides.
Therefore, the third side must be greater than 3 mm (10 mm - 7 mm = 3 mm) and less than 17 mm (10 mm + 7 mm = 17 mm).
Only 5 mm satisfies this condition.
So, the length of the third side is 5 mm.
