Answer 2

Answer:

AC = 10cm

Step-by-step explanation:

Given,

DE║BC                                                                        

AD = 2cm

DB = 5cm

AE= 4cm

To find, EC

ANSWER-

Let AC = x

DE ║ BC                                  (given)

$\frac{AD}{DB} =\frac{AE}{EC}$                                  (by B.P.T.)

$\frac{2}{5} = \frac{4}{x}$

$2x = 20$

$x =\frac{20}{2}$

$x = 10$

∴ AC = 10cm
