Answer:
Is not possible to build such triangle ( the 55 ft side is too long)
Step-by-step explanation:
There is no triangle that has the dimensions of 19 ft , 28 ft and 55 ft . If we think in the largest side , 55ft , there is no way to join the remaining sides since the largest possible segment that can be built with those is 19 ft + 29 ft = 47 ft < 55 ft
