Question

8. In the figure, BAD = CAD; AB = 3.4 cm, BD = 4 cm, BC = 10 cm then find AC?​

Answer 1

Answer :

Given,

AB = 3.4 cm, BD = 4 cm, BC = 10 cm

DC = BC – BD = 10 – 4 = 6 cm

In ΔACB, AD is the internal angle bisector of angle A.

By internal angle bisector theorem,

$\frac{ab}{ab} = \frac{dc}{bd}$

putting the value,

$ec = \frac{ae}{ad} \times db$

$= \frac{5}{4} \times 6$

$= 7.5cm$
