As astronomer observes that at point A on the planet Mercury at a particular time the sun is directly in line with point A and the center of the planet. At the same time, the sun’s rays form an angle of 5 with the vertical at point B on the surface of the planet. She determines that point B is roughly 213 km south of point A. Using this data, what will she calculate Mercury’s diameter to be? (See sketch.)
