Question

In figure AD is the bisector line of angle BAC AB=2cm AC=4cm BD=1.2cm Then the length of BC

Answer 1

Answer:

2.4

Step-by-step explanation:

∆ABC AD is a bisector line.

AB = 2cm, AC = 4cm and BD = 1.2cm

BD is the half of BC

Now, BD + DC = BC

i.e., 1.2cm + 1.2cm = 2.4cm

The length of BC is 2.4cm
