The segment is 8 cm longer than the second and the third is 4 cm shorter than the second by how many centimeters the first segment is longer than the third.
Let’s say that the second segment has a length of X cm. Since the first segment is 8 cm longer than the second, then the length of the first segment (X + 8) cm. The third segment is shorter than the second by 4 cm, and the length of the second X is 4) cm.In order to find how much the first segment is longer than the third, it is necessary to subtract the length of the third from the length of the first: X- (X-4) = X-X + 4 = 4
Answer: the first segment is 4 cm longer than the third.
