# Consecutive side length

Geometry Level 5

$$\triangle_{ABC}$$ is given that $3 \times \angle ABC+2 \times \angle BCA=180^{o}$ And three sides of this triangle are 3 consecutive integers. Find the length of these 3 side.

If the length of them are:

$\begin{eqnarray}\ AB & = & a\\ BC & = & b\\ CA & = & c \end{eqnarray}$ write it as $a^{b}+c!$ where $$c!$$ denotes the factorial notation
