I have no idea how to begin this problem, any help would be greatly appreciated.
As shown in the diagram, a ship is headed directly toward a coastline formed by a vertical cliff (segment BC) that is 80 meters high. At point A, from the ship, the measure of the angle of elevation to the top of the cliff (B) is 10°. A few minutes later, at point D, the measure of the angle of elevation to the top of the cliff has increased to 20°.
Determine the following to the nearest meter.
Segment DC
Segment AC
When I first tried, I got 36for segment DC and 123 for AC. I can't even begin to explain how I got those answers, but they were both wrong.
