Thus (A \approx 119^\circ) (measured from north through east). (a \approx 57.5^\circ), (A \approx 119^\circ).

$$\cos(90^\circ - \delta) = \cos(90^\circ - \phi)\cos(90^\circ - a) + \sin(90^\circ - \phi)\sin(90^\circ - a)\cos A$$ spherical astronomy problems and solutions

Used to find the angular distance between two stars or to convert between coordinate systems. Thus (A \approx 119^\circ) (measured from north through
