A highway whose primary directions are north south is being constructed along the west coast of a region At one point a bay obstructs the straight path of the road Since the cost of a bridge is prohibitive engineers decide to go around the bay The figure shows a diagram of the path that they decide on and the measurements taken If L 5 mi what is the length of highway needed to go around the bay Bay 140 B 135 E D 1 8 mi C 1 8 mi The total length of the highway needed to go around the bay is about miles Do not round until the final answer Then round to two decimal places as needed
