The answer is going to be 28. hope that helped
Apply the cosine double angle identity to get:
Cos 2PI/3
3(d + 11) = 6(d + 33)
So you have: 3d + 33 = 6d + 198
which is: -3d = 165
or d = -55
So you have <em>only one answer.</em>
525,600 minutes in a year
3,330,000 * 525,600 = answer
Type it into a calculator and you'll have your answer
I think it's 21% when rounded to a whole number
