Sines and cosines are trigonometric identities
The corresponding match of the sine or cosine values are:
- Cos(57) = Sin(33)
- Sin(43) = Cos(47)
- Cos(43) = Sin(47)
- Sin(32) = Cos(58)
<h3>How to determine the sine and cosine values</h3>
Given that:
Then:
This means that, angles a and b are opposite values
For cos(57),
The sine value is: sin(33)
This is so because:
57 + 33 = 90
When the above formula is applied to the remaining functions, we have:
sin(43) = cos(47)
cos(43) = sin(47)
sin(32) = cos(58)

Answer:
9/64
Step-by-step explanation:
So, we need to find the probability of drawing a blue marble the first time. There are a total of 8 marbles, and 3 blue marbles. So, the probability for the FIRST PULL will be:
3/8
Now, you REPLACE it meaning the value will stay the same. So now you just multiply.
3/8 * 3/8 = 9/64
Hope this helps !!

Answer:
Step-by-step explanation:
1) First, we figure out the number of blue and green marbles (27 each)
2) Subtract the 6 blue and 3 green marbles. We now have 21 blue marbles and 24 green marbles.
3) Since we want to have more blue marbles while taking out the <em>minimum</em> number of green, we're going to take out green marbles out until there's one less than blue. Because there's 21 blue, we want 20 green. We've taken out 4/13 marbles so far.
4) Now, we're going to take 1 marble out of both the greens and blues until we have 17 blue and 16 green. We've now taken out 12/13 marbles. We can't make the 13th marble a blue one, otherwise we even them out, so we'll take another green. Now we have 17 blue and 15 green.
5) Count the number of greens you've taken out, and voila!
