6C.7

How can we find the pKa/relative strength for +NH3OH and (CH3)2NH2+, since they aren't listed in the tables we're asked to refer to?

NH3OH+ is the conjugate acid of hydroxylamine (NH2OH) which is given in Table 6C.2. (CH3)2NH2+ is the conjugate acid of dimethylamine, (CH3)2NH which is also given in Table 6C.2. Just do 14 - pKb to find pkA.
