Joe is looking out the window of a building while talking to John, who is looking out the window of an adjacent building. Joe is 9.4 m above the ground below and distance between the two buildings is 17.0 m. In order for Joe to look directly at John he needs to look at an angle that is 14.7 degrees below the horizontal. (This is the angle represented as the Greek letter theta in the diagram.) Assuming that the ground between the two buildings is level, how high is John above the ground below (in m)?
