Campbell Soup said sales of soups and fresh foods declined in the most recent quarter and its shares decl$1.40, or 2.9 percent, to $46.31.

Then the following values will be readily deduced from the figure:— AD = a cos decl.

CX = AC = AD cos lat. = a cos decl. cos lat.

PN = CV = CX cos ACX = a cos decl. cos lat. cos ACX.

From the spherical triangle PZS, we have cos ZS = cos PS cos ZP + sin PS sin ZP cos ZPS but ZS = zenith distance = 90� - altitude ZP = 90� - PR = 90�- latitude PS = polar distance = 90� - declination, therefore, by substitution sin alt. = sin decl. sin lat. + cos decl. cos lat. cos ZPS ...
