Applying the triangle inequality theorem, the best representation for the third side is: A. 2 < s < 18.
According to the triangle inequality theorem, the sum of any two sides of a given triangle must be greater than the length of the measure of the third side of the triangle.
Thus, given an acute triangle has sides, 8 cm and 10 cm, applying the triangle inequality theorem, the range of sides would be calculated as shown below:
10 - 8 < s > 8 + 10
2 < s > 18
The range of values for the third side is: A. 2 < s < 18.
