In △ABC, AB = 3 cm, AC = 4 cm and AD is the bisector of ∠A. Then, BD : DC is —
9:16
16:9
3:4
4:3
By angle bisector theorem, BDDC = ABAC =34
So, BD : DC = 3 : 4.
In △ABC, AB = 3 and, AC = 4 cm and AD is the bisector of ∠A. Then, BD : DC is —
In △ABC, AB=3 cm, AC=4 cm and AD is the bisector of ∠A. Then, BD:DC is
