According to the Triangle Inequality Theorem, in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
In this case, AB = 3 cm, BD = 5 cm. Let's find the possible lengths of AD:
1. AD + AB > BD
AD + 3 > 5
AD > 2
2. AD + BD > AB
AD + 5 > 3
AD > -2 (Since AD cannot be negative, ignore this inequality)
Therefore, the possible lengths of AD are 2 cm and greater.
So, the two possible lengths of AD are:
A. 4 cm
C. 7 cm
