To find the length of PM, we can subtract the length of AP from the length of AM.
1. Given that AP = 12.2 and AM = 23.3, we need to find PM.
2. To find PM, we can subtract the length of AP from the length of AM:
PM = AM - AP
3. Substituting the values, we have:
PM = 23.3 - 12.2
4. Calculating the difference, we get:
PM = 11.1
Therefore, the length of PM is 11.1.
