Question

In ΔABC AD is the bisector of A .

If AB = 6.4 cm, AC = 8 cm and BD = 5.6 cm, Find DC .

Answer 1

Answer:

7

Step-by-step explanation:

AB/AC =BD/DC

so 6.4/8=5.6/DC

DC=7

Answer 2

Answer:

in triangle abc AD is the bisector of Angle A.

so by angle bisector theorem we get

BD/DC = AB/ AC

5.6/DC = 6.4/ 8

6.4DC = 44.8

DC = 44.8/6.4

DC = 448/640

DC = 7
