In triangle ABC, AD is the bisector of angle BAC. If AB=10 cm, AC=14 cm and BC=6 cm, find BD and DC.
Pls solve it without angle bisector property..pls...
Dear Student,
In ABC we have AD as bisector of BAC
Therefore,
Now, AB = 10cm , AC = 14cm , BC = 6cm
Let BD = x cm, then CD = (6 - x) cm
Now,
5 (6-x) = 7x
30 - 5x = 7x
12x = 30
x = 2.5 cm
Hence, BD = 2.5 cm and CD = 6 - 2.5 = 3.5 cm
Regards
