Math Question

Two photographs of the moon were taken at precisely the same time from two locations. The lunar angles of elevation at city A and at city B were measured as \( 51.6989^{\circ} \) and \( 51.7425^{\circ} \), respectively. The two cities are 398 kilometers apart. Calculate the distance to the moon from city A on this day, and compare it with the actual value of 406,000 kilometers. Disregard the curvature of Earth in this calculation. Not to scale. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Round to the nearest thousand as needed.) A. The distance to the moon from city A is about \( \square \mathrm{km} \), which compares favorably to the actual value.
