Let $P_1: y = x^2 + \frac{52}{5}$, and $P_2: x = y^2 + \frac{25}{10}$ be two parabolas in the Cartesian plane. Let $\mathcal{L}$ be a common tangent line to $P_1$ and $P_2$ with a rational slope. If $\mathcal{L}$ can be expressed as $ax + by = c$ where $a, b, c$ are positive integers with $\gcd(a, b, c) = 1$, determine $a + b + c$.
