Answer:

Vertices = 20

Step-by-step explanation:

Using the Euler's formula:

V - E + F = 2            ....[1]

where,

E is the number of Edges

V is the number of Vertices

F is the number of Faces.

As per the statement:

Edges: 43  

Faces: 25  

⇒E = 43 and F = 25

Substitute in [1] we have;

V-43+25 = 2

⇒V-18 = 2

Add 18 to both sides we have;

V = 20

Therefore, the number of vertices is, 20
