Question 1625Navigation General70% to pass
If the Sun's observed altitude is 27°12', the zenith distance is _______________.
AI Explanation
The correct answer is A) 62°48'.
The zenith distance is the angular distance between the zenith (the point directly overhead) and the observed celestial body. It is calculated by subtracting the observed altitude from 90 degrees. In this case, the observed altitude of the Sun is 27°12', so the zenith distance is 90° - 27°12' = 62°48'.
The other options are incorrect because: B) 152°48' is the incorrect supplement of the zenith distance, C) 43°12' is the incorrect complement of the observed altitude, and D) 27°12' is the observed altitude itself, not the zenith distance.
