Answer: The second side must be greater than 50.3 cm
Step-by-step explanation:
The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the length of the third side.
From the information given, the lengths of two sides are 26.9 and 77.2
Let x represent the length of the third side. Thus,
difference of two sides < x < sum of two sides
By substituting the values,
77.2 - 26.9 < x < 26.9 + 77.2
50.3 < x < 104.1
Thus, the possible length must be greater than 50.3
