Hope this helped :D

Answer 2

between 0 cm and 21 cm

Explanation:

BC could be anything between zero and 8+13=21 as per triangle inequality theorem:

0 < BC < AB+AC or

0 cm < BC < 21 cm

• The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
