# ​below is a pie chart for a set of data consisting of 5 items. the frequency of item A is 34 A=17% B=27% C=21% D=14% E=21% a)find the frequency of B ​b)draw the frequency table for the set c)find the angle of sector representing item C ​ ​

Dear student,

i) If 17% indicates frequency 34,
then 27 % = 34 / 17 * 27 = 54
Frequency of B is 54.

ii)
 Item % Frequency A 17 34 B 27 54 C 21 42 D 14 28 E 21 42 Total 100 200

iii) C = 21%
Whole circle = 360$°$
100 % = 360$°$
1 % = 360$°$ / 100
21 % = 360 $°$/ 100 * 21
C represents angle of 75.6$°$
