A triangle has two sides of length 5 and 19. What is the smallest possible whole-number length for the third side?

13

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is

difference of 2 sides < x < sum of 2 sides , that is

19 - 5 < x < 19 + 5

14 < x < 24

Thus the smallest whole number length of the third side is 13

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

3 is greater then both of those numbers
