During an instant observation at a place whose latitude is N38⁰29'42", the sun's apparent declination (already corrected for refraction and parallax) and the true altitude were determined to be N17⁰24'29" and 32⁰55'30", respectively. Determine the length (in angular units) of the three sides of the astronomical triangle formed by the sun, the observer's zenith, and the celestial pole.Assuming that the clockwise horizontal angle from the line to the sun is 275⁰15'35", determine the true bearing of the sun and of the line if the observation was done in the morning

Question
During an instant observation at a place whose latitude is N38⁰29'42", the sun's
apparent declination (already corrected for refraction and parallax) and the true altitude
were determined to be N17⁰24'29" and 32⁰55'30", respectively. Determine the length
(in angular units) of the three sides of the astronomical triangle formed by the sun, the
observer's zenith, and the celestial pole.Assuming that the clockwise horizontal angle
from the line to the sun is 275⁰15'35", determine the true bearing of the sun and of the line
if the observation was done in the morning.
