Which of the following set of numbers could not represent the three sides of a triangle

4,6,9
8,14,19
9,13,22
10,23,32

The set of numbers that could not represent the three sides of a triangle is:

10,23,32

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. However, in this set of numbers, 10 + 23 = 33, which is not greater than 32. Therefore, these numbers could not represent the sides of a triangle.
