6. Natalia and Sun are 14.5 m apart and looking up at the top of a radio tower. They are on the same side of the tower. If Natalia is looking up at an angle of 28°, and Sun is looking up at the tower at an angle of elevation of 31°, how tall is the tower to the nearest tenth of a metre? Assume their eyes are 1.6 m above the ground.
