Question Number 154434 by oustmuchiya@gmail.com last updated on 18/Sep/21

Answered by mr W last updated on 18/Sep/21

((BD)/(AB))=((AB)/(BC))  ⇒BD=((AB^2 )/(BC))=(8^2 /(16))=4

$$\frac{{BD}}{{AB}}=\frac{{AB}}{{BC}} \\ $$$$\Rightarrow{BD}=\frac{{AB}^{\mathrm{2}} }{{BC}}=\frac{\mathrm{8}^{\mathrm{2}} }{\mathrm{16}}=\mathrm{4} \\ $$
