What is Sexagesimal system in trigonometry?
Space and AstronomyIn the Sexagesimal system of measurement a right angle is divided into 90. equal parts called Degrees. Each degree is divided into 60 equal parts called Minutes, and each minute into 60 equal parts called Seconds. The symbols 1°, 1′, and 1″ are used to denote a Degree, a Minute, and a Second respectively. What
Is the cork you used alive?

How do you convert from bearings to degrees?
Space and AstronomyTo convert angle of bearing to degrees of a standard angle, subtract the bearing angle from 90°. If you end up with a negative answer, add 360°, and if your answer is greater than 360°, subtract 360° from it. For a bearing angle of 180°, the standard angle would be 270°.Sep 24, 2019 How do
