A scientist standing at the top of a mountain 2 mi above sea level measures the angle of depression to the ocean horizon to be 1.82 ° . Use this information to approximate the radius of the Earth to the nearest mile. ( Hint: The line of sight A B ↔ is tangent to the Earth and forms a right angle with the radius at the point of tangency.)
