5. Charlie's work to find the missing angle measure (to the nearest degree) is shown. What mistake did Charlie make? Charlie's work: 19 -1 tan = X 30 19 tan X 30/ -1 : 32° = 19 units 30 units

Albert lives in New Orleans. At noon on a summer day, the angle of elevation of the sun is 84. The window in Alberts room is 4.0 feet high and 6.5 feet wide. (Sec Figure 24.) a. Calculate the area of the floor surface in Alberts room that is illuminated by the sun when the angle of elevation of the sun is 84. b. One winter day the angle of elevation of the sun outside Alberts window is 37. Will the illuminated area of the floor in Alberts room be greater on the summer day, or on the winter day? Figure 24

Determine the answers to the following exercises which are based on corresponding parts. Identify the angle that corresponds with each angle listed. All dimensions are in millimeters.
