The azimuth is the angle formed between a reference direction ... i.e. the bearing 150 degrees clockwise from north. The reference direction, stated first, is always ...
For example, an angle of 30 degrees is already a reference angle, and an angle of 150 degrees also has a reference angle of 30 degrees (180° − 150°). Angles of 210° and 510° correspond to a reference angle of 30 degrees as well (210° mod 180° = 30°, 510° mod 180° = 150° whose supplementary angle is 30°).
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. [4] It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI brochure as an accepted unit. [5]
It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object. For a satellite orbiting the Earth directly above the Equator , the plane of the satellite's orbit is the same as the Earth's equatorial plane, and the satellite's orbital inclination is 0°.
The values of sine and cosine of 30 and 60 degrees are derived by analysis of the equilateral triangle. In an equilateral triangle, the 3 angles are equal and sum to 180°, therefore each corner angle is 60°. Bisecting one corner, the special right triangle with angles 30-60-90 is obtained.
A Quincunx or Quinduodecile or Inconjunct is an angle of 150°, which is 5 ⁄ 12 of the 360° ecliptic. Depending on the involved planets, an orb of ±3.5° is allowed. The symbol is the bottom radii of a hexagon, which is 1 ⁄ 2 a Sextile (60°) less than a semicircle; the internal angles are 60°.
The internal angle at each vertex of a regular dodecagon is 150°. ... These lower symmetries allows degrees of freedoms in defining irregular dodecagons. [6]
The angle of rotation from the black ray to the green segment is 60°, from the black ray to the blue segment is 210°, and from the green to the blue segment is 210° − 60° = 150°. A complete rotation about the center point is equal to 1 tr, 360°, or 2π radians.
