Answer:
[tex]d(A,B) = 18[/tex]
[tex]d(A,B) = 2[/tex]
Explanation:
Given
[tex]d(A,C) = 10[/tex]
[tex]d(C,B) = 8[/tex]
Required
[tex]d(A,B)[/tex]
It is possible that:
[tex]d(A,B) = d(A,C) + d(B,C)[/tex]
So:
[tex]d(A,B) = 10+8[/tex]
[tex]d(A,B) = 18[/tex]
Also, it is possible that:
[tex]d(A,B) = d(A,C) - d(B,C)[/tex]
So:
[tex]d(A,B) = 10 - 8[/tex]
[tex]d(A,B) = 2[/tex]
