Use Euler's formula to find the missing number. Vertices: 22 Edges: 34 Faces:?

a) 10
b) 12
c) 14
d) 16

We know that Euler's formula states that V - E + F = 2, where V is the number of vertices, E is the number of edges, and F is the number of faces. Plugging in the given values, we get:

22 - 34 + F = 2

Simplifying the equation, we get:

F = 14

Therefore, the missing number is c) 14.
