PLEASE HELP ASAP GIVING BRAINLEST

Answer 1

You have 6 faces:

F = 6

Counting edges:

You have 5 triangles --> 5 * 3 = 15 edges

You have 1 pentagon --> 1 * 5 = 5 edges

That would seem to be 20 edges, but obviously every edge is shared between the neighboring faces, so we have to divide this by 2.

E = 10

Euler's formula:

V - E + F = 2

Plug in your given values and solve for V:

V - 10 + 6 = 2

V - 4 = 2

V = 2 + 4

V = 6

Answer:

6 vertices
