Answer:
12
Step-by-step explanation:
in a triangle the sum of 2 sides must always be larger than the 3rd side.
our in other words, every side must be shorter than the sum of the other 2 sides.
or third side = x
19 < x + 8
therefore, 11 < x, x must be at least 12.
8 < x + 19 (that is true in any case)
x < 19 + 8 = 27
therefore, x cannot be longer than 26.
