The angle is typically measured in degrees from the mark of number 12 clockwise. The time is usually based on a 12-hour clock. A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute.
Usually, the screens are designed to facilitate greater viewing angles at the horizontal level, and smaller angles at the vertical level, should the two of them differ in magnitude. The viewing angle for some displays is specified in only a general direction, such as 6 o'clock or 12 o'clock.
The observer then measures or observes the angle made by the intersection of the line of sight to the longitudinal axis, the dimension of length, of the vessel, using the clock analogy. In this analogy, the observer imagines the vessel located on a horizontal clock face with the front at 12:00.
Time sight is a general method for determining longitude by celestial observations using a chronometer; these observations are reduced by solving the navigational triangle for meridian angle and require known values for altitude, latitude, and declination; the meridian angle is converted to local hour angle and compared with Greenwich hour angle.
One arcsecond is the approximate angle subtended by a U.S. dime coin (18 mm) at a distance of 4 kilometres (about 2.5 mi). [6] An arcsecond is also the angle subtended by an object of diameter 725.27 km at a distance of one astronomical unit, an object of diameter 45 866 916 km at one light-year,
To find the angle of a rotation, once the axis of the rotation is known, select a vector v perpendicular to the axis. Then the angle of the rotation is the angle between v and Rv. A more direct method, however, is to simply calculate the trace: the sum of the diagonal elements of the rotation matrix.

The gnomon is the triangular blade in this sundial.. A gnomon (/ ˈ n oʊ ˌ m ɒ n,-m ə n /; from Ancient Greek γνώμων (gnṓmōn) ' one that knows or examines ') [1] [2] is the part of a sundial that casts a shadow.
