Question

Ad is the bisector of angle bac if ab=9


c.m


a.c=12 and bc =7


c.m find bd and dc

Answer 1

Given:ab=9cm
ac=12cm
bc=7cm
As AD is the bisector si that it will meet at the midpoint of bc
Now therefore we can say that bd +dc=7cm
Let the length be x
As it will meet at point
We can say.2x=7
x=7/2
=3.5 cm
