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]
