To determine the possible lengths of the third side of the triangle, you 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.

So, for a triangle with sides of lengths 6 and 13:

- The third side must be greater than the difference between the lengths of the other two sides.
- The third side must be less than the sum of the lengths of the other two sides.

Therefore, the possible lengths of the third side can be:

6 + 13 > Third side > |6 - 13|

Solve for both inequalities:

6 + 13 > Third side 19 > Third side

|6 - 13| = |-7| = 7 7 < Third side

So, the third side must be greater than 7 and less than 19. Therefore, the possible lengths of the third side are any value between 7 and 19, exclusive.

- A triangle has corners at points A, B, and C. Side AB has a length of #32 #. The distance between the intersection of point A's angle bisector with side BC and point B is #12 #. If side AC has a length of #24 #, what is the length of side BC?
