    Answer:

    Given A -B-C the co-ordinate of point A is the smallest.If d(A,B) = 7.5, d(B,C):= 13,8 and the co-ordinate of point B is 8.5.

    So,

    d(AB) = co-ordinate of point B – co-ordinate of point A

    => 7.5 = 8.5 – co-ordinate of point A

    => co-ordinate of point A = 1

    d(B,C) = co-ordinate of point B – co-ordinate of point C or co-ordinate of point C – co-ordinate of point B

    But , If the co-ordinate of point B > co-ordinate of point C, the point C is behind the point A, then co-ordinate A is not the smallest. then,

    d(B,C) = co-ordinate of point C – co-ordinate of point B

    => 13.8 = co-ordinate of point C – 8.5

    => co-ordinate of point C = 13.8 + 8.5 = 22.3

    Step-by-step explanation:
