Question

If total degree of graph is 12 then the number of edges of graph are​

Answer 1

Answer:

Step-by-step explanation:

This requires more information because a face is a topological concept not a pure graph theory one. Graphs have vertices and edges. If you mention faces you have to specify a topology. If you are talking about the sphere, that is a polyhedra, then Euler's theorem says the number of vertices minus the number of edges plus the number of faces is 2.
