Answer:
(i) The length of AC is 32 units, (ii) The length of BC is 51 units.
Step-by-step explanation:
(i) Let suppose that AB and BC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:

Answer:
x=-7.5
Step-by-step explanation:
3x-2/4=2x-8
-2x -2x
x-2/4=-8
+2/4 +2/4
Put separate terms on each side
x=-7.5
Please correct me if I'm wrong
Hope this helps!
