Question

A triangle has two sides of length 19 and 3. What is the smallest possible whole-number length for the third side?

Answer 1

The answer is 7. Use the whole number length

Answer 2

17

Explanation:

You have length 19 and 3:

19-3 = 16 AND 19+3=22

You have a range of 16 and 22 and the smallest number between this specific interval is 17, you do not include 16 or 22 in the interval.
