given data
declination of star = -13.00º
latitude = 26.00º N
to find out
distance in degrees between the star and zenith
solution
we know the formula that is
latitude = star declination+ its zenith distance ....................1
and
zenith distance = latitude - star declination
zenith distance = 26 - ( -13 )
zenith distance = 26 + 13
zenith distance = 39 degree
