From a point A that is 141 ft above level ground, the angle of elevation to a top of a building (point 7) is 370 and the angle of depression to the base (point B) of the building is 120. Click to go forward, hold to see history C B Answer the following. Give exact answers. Decimal approximations will be marked wrong. Don't forget the degree symbol! (a) Determine the length of BC. BC = ft (b) Use Angle of Depression to determine the length of AC. AC = ft (c) Use Angle of Elevation to determine the length of TC. TC = ft (d) Use your answers above to determine the height of the building Height = ft
