Total number of students in university = 30,600
2% break 3 of the languages
Therefore, 2/100 × 30600 = 612 students break 3 of the languages in the University according to the counselor.
In a random sample of 240 students, 20 break 3 of the languages.
% = 20/240 × 100 = 8.33%

cos60° = 
cos60° =
= 
Multiply both sides by x
x × cos60° = 8, that is
x ×
= 8
Multiply both sides by 2
x = 16
