Answer:

29

Explanation:

A triangle has two sides of length 10 and 20. What is the smallest possible whole-number

length for the third side?

-----------------------------------------

  • The sum of lengths of any two sides of a triangle is always greater than the third side

so

10 + 20 = 30

any size smaller than 30 is fine, but ask for a whole number, so the answer is 29
