A contractor building eight ocean-front condominiums wants to maximize the view of the ocea for each unit. The side of the building facing the ocean is not built in a straight line parallel to the ocean ocean, but instead is built in a zigzag pattern as shown in the figure. Each condo has a window of length x facing the ocean at an angle of 70° from a line perpendicular to the ocean. a. Find the length x of each window. Round to the nearest foot. b. The windows facing the ocean are 8 ft high and x feet wide. By using the zigzag pattern how much more ocean-front viewing area does each window provide than if the windows were parallel to the ocean? Round to the nearest square foot. 70 Unit Unit Unit Unit Unit Unit Unit Unit 4 6. 256 ft
