Question

In AABC, AD is the internal bisector of ZA.
If BD=5 cm, BC = 7.5 cm, then find AB: AC.
(a) 2:1
(6) 1:2
(c) 4:5
(d) 3:5​

Answer 1

Answer:

ans

Step-by-step explanation:

hey there. in. ∆ abc, if ad is angel bisector of angel a then , ab:ac =bd:DC (by internal angel bisector theorem)

then,bd=5cm,bc=7cm

DC=7.5-5=2.5

ab:ac=bd:bc =5:2.5=2:1
