MO is twice as long as MN. NO= 36 cm. What lengths must NM be between in order for MNO to be formed?

Nataliya [291]

Answer:

Length of NM is 36 cm

Step-by-step explanation:

Length of MN + Length of NO = Length of MNO (Or only MO)

$X + 36 = 2X$

$2X - X = 36$

$X = 36$ cm

Thus, length of MN is equal to length of NO i.e 36 cm

The line MNO has point N, that bisect it into two equal half.

Thus, the line MNO has two parts

Total length of line MNO = MN + NO = $36 + 36 = 72$ cm
