Answer:
13
Step-by-step explanation:
let the third side be x, then the possible values for the third side is
difference of 2 sides < x < sum of 2 sides, that is
19 - 7 < x < 7 + 19
12 < x < 26
The possible integer values are
13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25
That is a total of 13 integer values
