Recall the formula for the sum of the interior angles of an n-sided polygon: \(\text{Sum} = (n - 2) \times 180^\circ\).
Identify the number of sides of the polygon, which is given as \(n = 19\) for a 19-gon.
Substitute \(n = 19\) into the formula: \(\text{Sum} = (19 - 2) \times 180^\circ\).
Simplify the expression inside the parentheses: \(19 - 2 = 17\).
Multiply \(17\) by \(180^\circ\) to find the sum of the interior angles: \(17 \times 180^\circ\).
