Answer 1

Answer:

in ΔABC and ΔADE

∠B=∠D                (corresponding angles)

∠C=∠E                 ("")

ΔABC≈ΔADE

AD/AB=AE/AC=DE/BC             (corresponding parts of similar Δs)

⇒AD/AB=DE/BC AND AE/AC=DE/BC

⇒2.4/AB=2/5    AND 3.2/AC=2/5

⇒12=2AB           AND       16=2AC

⇒AB=6 cm         AND        AC=8 cm

NOW, AC=AE+EC

          ⇒ AC-AE=CE

            ⇒8-3.2=CE

            ⇒4.8 cm = CE

ALSO, BD=AB-AD

           ⇒BD=6-2.4= 3.6 cm
