In a certain triangular park, the sides are represented by the lengths $a$, $b$, and $c$, where $a$, $b$, and $c$ are the lengths of the sides of the triangle in meters. Is it possible to form a triangle with these sides?
Statement (1): $a + b = 15$ and $c = 10$.
Statement (2): $a = 8$, $b = 6$, and $c = 5$.
