Three points O, P and M are given on the straight line; and point O lies between P and M.

Three points O, P and M are given on the straight line; and point O lies between P and M. It is known that OM = 14 cm; OP = 8 cm; Find PM.

Given:
the line a belongs to the points O, P and M,
point O lies between P and M,
OM = 14 centimeters
OP = 8 centimeters.
Find the length of the segment PM -?
Solution:
Consider line a. Since point O lies between P and M, therefore the length of the segment PM is equal to:
PM = PO + OM;
PM = 8 + 14;
PM = 22 centimeters.
Answer: the length of the segment PM = 22 centimeters.
