Si la altura de un astro es 33º (señale la respuesta correcta):If the altitude of a celestial body is 33º (select the correct answer):
Show the answer
Correct answer: b) Its zenith distance will be 57º.
Why it is correct
Zenith distance (z) is the complement of true altitude (a): z = 90° − a. Therefore, if a body’s altitude is 33°, its zenith distance is 90° − 33° = 57°.
Why the others are not
- a) Declination is an equatorial coordinate and is not the complement of altitude.
- c) Codeclination is the complement of declination (90° ± δ), not of altitude.
- d) Azimuth cannot be determined from altitude alone.
How to work it out in the exam
- Zenith distance: z = 90° − altitude = 90° − 33° = 57°.
