Spanning tree question with graph G on vertices a to f An undirected graph *G* has 12 edges. Find the number of vertices, if the degree of each vertex in *G* is 2. The melting point of ice and boiling point of water in Celsius scale is 0^(o) and 100^(o) Centigrade respectively, and in Fahrenheit scale is 32^(o) and 212^(o) Fahrenheit respectively.If the change in Fahrenheit scale varies linearly with respect to Celsius scale, then at what temperature (in ^(o) Centigrade) both the scale read the same?
