A large region of forest has been infested with gypsy moths. The region is triangular, as shown in the figure. From vertex A, the distances to the other vertices are 31 miles south and 10 miles east (for vertex B), and 20 miles south and 28 miles east (for vertex C). Use a graphing utility to find the area (in square miles) of the region. X square miles W E 20 mi 31 mi C 10 mi 28 mi-

On your scratch paper, graph the following four points: A (0, 0), B(2, 4), C(7, 4), and D(5, 0). Connect the points to form a convex quadrilateral. Identify the quadrilateral as precisely as possible and tell me why you classified it the way you did.

Read all directions before answering a question. This assignment is conceptual in nature so no work is needed BUT be sure to be clear and state all answers in complete sentences where needed. Write answers on this sheet. 1) Determine how many vertices and edges the graph has and the degree of each vertex. State the degree next to the vertex OR state the vertex label letter and the degree in the space to the right of the graph. A B E с D # of vertices = # of edges =
