Answer 2

To find the length of BC, we can use the triangle inequality theorem, which states that 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, we have AD = 40 mm, AC = 20 mm, and BD = 32 mm. Let's consider triangle ABC:

AC + BC > AB 20 mm + BC > 40 mm

BC > 40 mm - 20 mm BC > 20 mm

Similarly, let's consider triangle BCD:

BC + CD > BD BC + 32 mm > 40 mm

BC > 40 mm - 32 mm BC > 8 mm

Therefore, the length of BC must be greater than 20 mm and greater than 8 mm. However, we cannot determine the exact length of BC without additional information or geometric constraints.
