We can use Euler's formula to find the missing number. Euler's formula states that for a connected planar graph, the number of vertices (V), edges (E), and faces (F) are related by the equation V - E + F = 2.
Given that the number of vertices is 13 and the number of edges is 28, we can substitute these values into the formula:
13 - 28 + F = 2
Simplifying the equation:
F = 2 + 28 - 13
F = 17
Therefore, the missing number of faces is 17.
