Answer 2

To find the length of BC (ВС), we can use the triangle inequality theorem. According to the theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, AC is given as 19 dm, BD as 17 dm, and AD as 32 dm.

Let's apply the triangle inequality theorem to the triangle ABD:

AB + BD > AD AB + 17 dm > 32 dm AB > 32 dm - 17 dm AB > 15 dm

Now, let's apply the triangle inequality theorem to the triangle BCD:

BC + CD > BD BC + 32 dm > 17 dm BC > 17 dm - 32 dm BC > -15 dm

Since the length of a side cannot be negative, we can conclude that BC must be greater than 0 dm.

Therefore, BC > 0 dm.
