Question

In given fig ,AD is bisector of angle A. If BD =4cm ,DC=3cm and AB =6 cm.determineAC

Answer 1

Here, we can see that ∠BAC is bisected by AD where AD touches BC at D. BC=BD+DCwhere, BC=3cm. We also have the values of adjacent sides AB=6cmand AC=5cm.

These satisfy the requirements of angle bisector theorem. Then, by the theorem, we have:

ABBD=ACDC

⇒DC=AC∗BDAB=5∗36=2.5cm

Answer 2

Answer:

The Above Given answer is wrong and this is correct  explaination so plz... mark me as brainlist

Step-by-step explanation:

In Triangle ABC AD bisects Angle BAC SO WE KNOW THAT:

So this Mean that

BD/DC = AB/AC

NOW, AC = AB*DC

AC = 6*3/4

Hence , AC = 4.5 cm
