On the segment KM with a length of 34 points A and B were marked so that KA 21 cm BM 18 cm what is the length of segment AB?
Let us find out the sequence in which the points are located on the segment.
1 case. K – A – B – M.
The KM segment consists of the lengths of the following segments: KM = KA + AB + BM.
By condition: KM = 34, KA = 21, VM = 18. Then:
34 = 21 + AB + 18 – express and calculate AB.
AB = 34 – 21 – 18;
AB = – 5 – received a negative value, the answer is not correct.
2 case. K – B – A – M.
The KM segment consists of the lengths of the following segments: KM = KA + VM – AB.
AB = – (34 – 21 – 18);
AB = 5.
