If sinα=cosß it means that ß=90-α. This also means that α+ß=90 so we can say:
4k-22+6k-13=90
10k-35=90
10k=125
k=12.5°
...
The above identity comes up a lot, and is one worth committing to memory for sure.
sinα=cos(90-α) or vice versa cosα=sin(90-α)
D is the answer because 17.10/.45=38 cups so 38*.10=3.80
100 - 45 - 20 (0.2 = 20%) - 12.5 (1/8 = 12.5%) = 22.5%

Answer:
32 people
