Question

on a number line , point A,B and C are such that d(A,C)=12, length (B,C)=4.5, then length (AB)= ?​

Answer 1

Step-by-step explanation:

Given: On a number line, points A, B and C are such that d(A,C) = 10, d(C,B) = 8

To Find : d(A, B) considering all possibilities.

Solution

31/2 = 3 ways (A in middle, B in middle or C in

Middle)

A B C

AC = 10 BC = 8 => AB = AC - BC = 10-8=2 AC B B A C (not Possible) as AC > BC

AB= AC + BC = 10 + 8 = 18

AB= 2 or AB = 18
