Question

BA=7см СК=9дм АК=22 дм Ас-? Вс-?

Answer 1

ВС=АК-АВ-СК
ВС=22дм-7см-9дм=12дм3см
АС=АВ+ВС
АС=7 см+12дм3см=13дм

Answer 2

To find the lengths of segments AC and CS, we need to apply the segment addition postulate. The segment addition postulate states that if three points A, B, and C are collinear, then the distance between A and C can be found by adding the distances between A and B and B and C.

Given: BA = 7 cm SK = 9 dm (1 dm = 10 cm, so SK = 90 cm) AK = 22 dm (AK = 220 cm)

Using the segment addition postulate, we can find AC: AC = AB + BC

Since AB = BA = 7 cm and BC = CK = SK = 90 cm, we have: AC = 7 cm + 90 cm = 97 cm

Therefore, AC = 97 cm.

To find CS, we can again apply the segment addition postulate: CS = CK + SK

We know CK = SK = 90 cm, so: CS = 90 cm + 90 cm = 180 cm

Therefore, CS = 180 cm.
