So one right angle = 100 x 100 minutesIn Centesimal system, 1 right angle = 100 grades and one grade = 100 minutesSo one right angle = 90 x 60 minutes in Sexagesimal system, 1 right angle = 90 degrees and one degree = 60 minutes
Hence, from these :
Ratio in Sexagesimal : Centesimal = (90 x 60) : (100 x100) = 27 : 50Santosh Bhandari
dear students i think this is better
Solution by Santosh Bhandari
If M1 and M2 be the minutes of any angle in degree and grade measurement system, then prove
=
Solution;
M1 and M2 be the minutes of any angle in degree and grade measurement system.
M1 = )
