Answer:
Step-by-step explanation:
Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get
![\frac{BD}{AD}=\frac{DC}{BD}](https://tex.z-dn.net/?f=%5Cfrac%7BBD%7D%7BAD%7D%3D%5Cfrac%7BDC%7D%7BBD%7D)
⇒![(BD)^{2}=DC{\times}AD](https://tex.z-dn.net/?f=%28BD%29%5E%7B2%7D%3DDC%7B%5Ctimes%7DAD)
⇒![(BD)^2=9{\times}16](https://tex.z-dn.net/?f=%28BD%29%5E2%3D9%7B%5Ctimes%7D16)
⇒![BD=\sqrt{144}](https://tex.z-dn.net/?f=BD%3D%5Csqrt%7B144%7D)
⇒![BD=12 cm](https://tex.z-dn.net/?f=BD%3D12%20cm)
Thus, the length of altitude is: 12 cm.
Now, ![\frac{AB}{AD}=\frac{AC}{AB}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BAD%7D%3D%5Cfrac%7BAC%7D%7BAB%7D)
⇒![(AB)^{2}=220](https://tex.z-dn.net/?f=%28AB%29%5E%7B2%7D%3D220)
⇒![AB= 14.83 cm](https://tex.z-dn.net/?f=AB%3D%2014.83%20cm)
Also, ![\frac{BC}{DC}\frac{AC}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7BDC%7D%5Cfrac%7BAC%7D%7BBC%7D)
⇒![(BC)^{2}=400](https://tex.z-dn.net/?f=%28BC%29%5E%7B2%7D%3D400)
⇒![BC=20 cm](https://tex.z-dn.net/?f=BC%3D20%20cm)
Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.
