The answer depends on the information that you have: it could be the sine rule or the cosine rule.
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.
By using the cosine rule in trigonometry the third side works out as 7.97cm rounded to 3 significant figures.
The minimum third side length of a triangle having one side of 11 and another side of 5 is 6.

No. The sum of the lengths of two sides of a triangle must always at least slightly exceed the length of the third side, and the given numbers do not conform to this rule.
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
The minimum third side length of a triangle having one side of 11 and another side of 5 is 6.
The length of the third side of this triangle must be greater than 1 foot and less than 5 feet, and the third side would be either 2 feet or 3 feet if it were an isosceles triangle.
If the third side is the hypotenuse of a right triangle, it is 10.0
If you have angles, use the sine rule: a/sin A = b/sin B = c/sin C a denotes the side, A the angle opposite the side.
The rule with triangles is that if you add the two shortest sides together, the third side should not be above the sum. Another rule is if you subtract the longest of the two sides with the shortest side, the third side should not be below the difference. In this case, 6+8 = 14. 10 is below 14. 8-6 = 2. 10 is above 2. A triangle with the sides of 6, 8, and 10 is possible.
