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:
f(2) =30
Step-by-step explanation:
f(1)=15
f(n)=f(n-1)*n
Put in n=2
f(2)=f(2-1)*2
= f(1) *2
= 15*2
=30
