The third side of the triangle must be between 10 inches and 18 inches (the sum of the lengths of the two known sides).
Therefore, the possible dimensions for the third side are 8 inches, 9 inches, 10 inches, 11 inches.
However, the third side of a triangle must be less than the sum of the other two sides.
4 + 14 = 18
So the third side must be 8 inches.
Therefore, the correct answer is 8 inches.
The lengths of two sides of a triangle are 14 inches and 4 inches. Which of the following dimensions is the third side of this triangle?
