• Decide whether the triangles are similar. If so, determine the appropriate expression to solve for x.Triangles ABC and EDF, where triangle ABC has angle A measuring 47 degrees, angle C measuring 62 degrees, side AC labeled as y, side AB labeled as w, and side BC labeled as x and triangle EDF has angle D measuring 71 degrees, angle E measuring 47 degrees, side DE labeled z, side EF labeled u, and side DF labeled r The triangles are not similar; no expression for x can be found. ΔABC ~ ΔDEF; x equals r times w over u ΔABC ~ ΔEDF; x equals r times w over u ΔABC ~ ΔEDF; x equals r times w over z

• You are constructing a triangular sail for a one-person sailboat. For support, a horizontal steel pole will run along the base of the sail and a vertical steel pole will run from the base to the top of the sail. In order for the sailboat to function properly, the combined weight of the poles cannot exceed 80 pounds. If the steel poles weigh 5 pounds per foot, what is the area of the largest sail you can build? Fully justify your answer; in particular, you must show that the area you found is indeed the largest possible.
