According to Euler's formula, for any polyhedron (a solid with flat faces), the number of faces (F), vertices (V), and edges (E) are related by the equation F + V - E = 2.
Plugging in the known values, we get:
25 + 17 - E = 2
Simplifying this equation, we get:
42 - E = 2
Subtracting 42 from both sides, we get:
-E = -40
Dividing both sides by -1, we get:
E = 40

Therefore, the missing number of edges is d) 40.
