Consider the graph with vertex set (A, B, C, D, E) and edge list AC, BC, BD, DD, DE, EE. Without drawing a picture of the graph, answer parts (a) through (d) (a) List all the vertices adjacent to D. (b) List all the edges adjacent to BD. (c) Find the degree of D. (d) Find the sum of the degree of the vertices. (a) List the vertices that are adjacent to D. (Use a comma to separate answers as needed.) (b) List the edges that are adjacent to BD. (Use a comma to separate answers as needed.) (c) deg(D) = (Type a whole number.) (d) The sum of the degrees of the vertices is (Type a whole number.)
