In a pentagonal pyramid you have 6 vertices and 6 faces. find the number of edges using euler’s theorem

The number of edges is 10

Step-by-step explanation:

we know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

we have

substitute the values

solve for E

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

you can use a^2+ b^2=c^2
