Answer:

AD is bisector of ∠BAC

⇒ Ratio at D is c:b where

c=AB=

(3−5)

2

+(2−3)+(0−2)

2

=

4+1+4

=

9

=3

b=AC=

(3+9)

2

+(2−6)

2

+(0+3)

2

=

144+16+9

=

162

=13

for point D

x=

c+b

c(−9)+b(6)

=

3+13

3(−9)+13(5)

=

16

38

=

8

19

y=

c+b

c(6)+b(3)

=

3+13

3(6)+13(3)

=

16

57

z=

c+b

c(−3)+b(2)

=

3+13

3(−3)+13(2)

=

16

17

Hence, point D is [

8

19

,

16

57

,

6

17

]
