Alfred is trying to reach across the edge of the building with a ladder that is 25 ft tall. He needs to figure out what is base across the lower building at an angle of depression of 56 degrees.
Alfred went down the building to find the measurement of one angle of his windows. He has 40 ft on one side and 35 ft on the other side.
Alfred decided to explore around his city hall and wanted to measure how tall the building was. One side was 80 ft but one side is unknown. The angle of elevation is 45 degrees. What is the missing side that Alfred needs to find?
