Question

In triangle ABC,DE//AB.if CD=3cm .Ec = 4vmBc =6cm Then find DA

Answer 1

Step-by-step explanation:

CD=3cm

EC=4cm

BC=6cm

DA=?

So,

DE || AB

So, CB =CE + EB

6 = 4+ EB

EB = 2cm

And DE || AB

So

$\frac{cd}{ad} = \frac{ce}{eb}$

$\frac{3}{ad} = \frac{4}{2}$

$ad = 3 \times 2 \div 4$

$ad = 6 \div 4$

$ad = \frac{3}{2} cm$
