Recall the double angle identity for cosine:
It follows that
Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,
but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...
In order to solve this problem you need to do the following:
3 days = 2 blankets
14/2=7= 7 days
so it will take 7 days for Grandma Jean to make 14 blankets.
