express

Dear Student,

 

(i) In Centesimal measure:

100 Grade = 90^o;

1 minute = 100 seconds;

and 1 Grade = 100 minutes

 

Hence 45^o = 50 grades

20' = 0.2 grades

and 10'' = 0.001 grades

So, 45^o20'10'' = 50 + 0.2 + 0.001 = 50.201 grades.

 

(ii) Also, the relation between Grade (G), Degree (D) and radian (C) is as follows:

D/180  = G/200  = C    

=> In radians;

45^o20'10'' = 50.201 grades = 50.201/200 radians= 0.251 radians
