The value of an n-sided polygon symbol containing a natural number A is equal to the integer part of the decimal representation of the fraction $\frac{A}{n}$.
Example: $\widehat{6} = 9 = 2$
Let AB be a two-digit natural number, and
$$\langle \mathrm{AB} \rangle = 19 = \mathrm{AB}$$
Accordingly, what is the sum $\mathrm{A} + \mathrm{B}$?
A) 6
B) 7
C) 8
D) 9
E) 10
