Respuesta :

Answer:

its length is greater than 3cm but less than 19cm

Step-by-step explanation:

all triangles have to have at least two sodes thr same length

Answer:

The last statement is true.

Step-by-step explanation:

In a triangle the sum of any 2 sides must be greater than the other side.

First choice: 8 + 3 = 11 whereas  8 + 3 should be > than third side so this statement  (it's length is 3 cm) is false.

Second choice: 8 + ( less than 3) is less than 11 so this statement is false

Third  choice: 19 = 8 + 11 but the side is > 19 so this statement is false

Fourth choice:   Let third side have length 4, then 8 + 4 > 11 and if it has length 18.9 then 8 + 11 > 18.9 so this statement is true.
