AB = AC + CB.
Let’s find what the segment СB is equal to. According to the condition of the problem, the CB segment is 3 times longer than the AC segment. Means:
СB = 5 * 3 = 15 cm.
Let’s find what the segment AB is equal to (we add the lengths of the two segments of which it consists):
AB = 5 + 15 = 20 cm.
Answer: the segment AB is 20 cm.
