Please explain the centesimal, radians, sexagesimal system in the measurement of angles!! Trigonometry class 10 . Plz help me guys!! soon pls.....
And the best ans... will be marked as the " Brainliest" one!!!...........
Answers
1)Sexagesimal System: In Sexagesimal System, an angle is measured in degrees, minutes and seconds.
1right angle= 90 degrees
1 degree= 60 minutes
1 minute = 60 seconds
2) Centesimal System: In Centesimal System, an angle is measured in grades, minutes and seconds. In this system, a right angle is divided into 100 .
1right angle= 100grades
1 degree= 100minutes
1 minute =100 seconds.
3)Radians
A radian is an angle subtended at the center of a circle by an arc whose length is equal to the radius.
Degrees. Radians.
0°. 0.
30°. π/6.
45°. π/4.
60°. π/3.
90°. π/2.
120°. 2π/3.
