The third side of a triangle must be greater than the absolute difference of the two given sides and less than the sum of the two given sides. In this case, the third side must be greater than |7-9| = 2 and less than 7+9 = 16. Therefore, the possible lengths for the third side of the triangle could be any value greater than 2 and less than 16.

The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
10
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
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.
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.

The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
Any triplet provided only that any two lengths are greater than the third.
10
The last side length could be between 4 units and 10 units inclusive.

No. The sum of any two lengths must be greater than the third length.
If the lengths of each pair of them add to more than the length of the third, they can form a triangle. If not, they cannot.
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
The length of the third side could be between 7 feet and 23 feet due to the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
If (and only if) the length of each pair of sides is greater than the third side, then it is possible to make a triangle.
