To find the distance to the sun, we need to know the distance to the moon. Here is a way to estimate that distance: When the moon is seen at its zenith at a point A on the earth, it is observed to be at the horizon from point B (see the following figure). Points A and B are 6155 mi apart, and the radius of the earth is 3960 mi. earth moon 6155 mi B (a) Find the angle 0 in degrees. (Round your answer to two decimal places.) Enter a number. (b) Estimate the distance from point A to the moon. (Round your answer to the nearest thousand miles.) X thousand miles
