Given a graph with vertices and edges. We denote by e the total number of edges and by v the total number of vertices. The Euler formula says that if we let r be the total number of regions that are created when drawing a representation of the graph, then r=ev 2. For a graph with 10 vertices and the degree of each vertex is 5, find the number of edges and the number regions in the graph. Hint: use the handshake theorem seen in class to compute the number of edges
