Question

if A-C-B and D (A, B)= 15,d (B,C)= find D ( A,B)​

Answer 1

Step-by-step explanation:

Given, A-B-C

D(AC)=15

D(BC)=6

to find D(AB)

solution: D(AB)=D(AC)-D(BC)

=15-6

=9

Answer 2

Step-by-step explanation:

we have d(A, C)=17

d(B, C)= 6.5

now d(A, C)=d(A, B) +d(B, C)

so d (A, B) =d(A, C) -d(B, C) =17 - 6.5

d(A, B) =10.5
