41. An archaeological team is excavating artifacts from a sunken merchant vessel on the ocean floor. To assist the team, a robotic probe is used remotely. The probe travels approximately 3,600 meters at an angle of depression of 58.2 degrees from the team’s ship on the ocean surface down to the sunken vessel on the ocean floor. The figure shows a representation of the team’s ship and the probe. How many meters below the surface of the ocean will the probe be when it reaches the ocean floor? Justify your answer and give it to the nearest hundred meters. 58.2
