Find x, the angle of depression (measured in degrees) from the top of a lighthouse that is 173 ft above water level to the waterline of a ship 4835 ft off shore. Round your answer to the nearest hundredth of a degree.

Answer 1

tan(tetha)=173/4835=0.002688728

tetha=arctan(0.002688728)=0,1540524°

tetha=0.15°

Answer 2

173/4835=0.03578076525336091

arctan(0.03578076525336091=2.049212625°
