On the AM beam, the segments AB and AC were laid, AC = 89 cm Find the length of the segment BC if AB is 15 cm longer than AC.

Since AC = 89 centimeters, and AB is 15 centimeters longer than AC, by condition, we can find the length AB:
AB = 89 + 15 = 104 (centimeters) – the length of the segment.
It follows from this that the segment AB is longer than the segment AC, that is, point B is located further than point C in relation to A. Therefore, to find the segment BC, we must from the length of the larger segment, in our case it is the segment AB, subtract the length less than the segment, segment AC, the difference between them will be the length of the segment BC, since it is located between segments AB and AC, in the middle between them. Let’s calculate:
BC = AB – AC = 104 – 89 = 15 (centimeters) – the length of the segment BC.
Answer: BC = 15 centimeters.
