Final answer:
Using the Angle Bisector Theorem, we can find the value of x and the length of BD using the given equation BD/AB = CD/AC. Substituting the values and performing cross-multiplication, we find that x = 48/7 and the length of BD is 48/7 units.
Step-by-step explanation:
Applying the Angle Bisector Theorem, we can find the value of x and |BD| (length of BD) as follows:
- Using the Angle Bisector Theorem, we have BD/AB = CD/AC.
- Substituting the values BD = x, AB = 12, CD = 18, and AC = 7 into the equation, we get x/12 = 18/7.
- Cross-multiplying and solving for x, we find that x = 48/7. Therefore, the value of x is 48/7 and the length of BD is 48/7 units.
Hence, x = 48/7 and |BD| = 48/7.
