'Pi' ( π ) is the ratio of the circumference of a circle to its diameter.
The exact value of 'pi' can't be completely written with numbers, so whenever
we use 'pi', we always use an approximation.
Answer:
Cos(A)=0.82
Tan(A)=0.696
Step-by-step explanation:
A=sin^- (4/7)
=34. 85
Cos (A)
Cos(34.85)=0.82
Tan(A)
Tan(34.85)=0.696
200 of them are men. 2/3=200/300. 75 are women. 1/4 is equal to 75/300. We can determine the rest by adding the men and women. 200+75=275. 300-275=25. 25 of the passengers are children.
