When a structure has resonance and you are calculating the enthalpy for its formation, how do you know whether to use the bond formation enthalpy for its single, double, or triple bonds?

My TA said that Lavelle will most likely provide the average bond enthalpies for resonance structures, as in the average of the single, double, and triple bonds, so I do not think that we will have to worry about the individual bonds.

In addition, here is a chart with some common average bond enthalpies if you need it:
