2 answers:
Answer:
Two negatives make a positive.
-75 - (-20) = -75 + 20
Do the math now:
-75 + 20 = -55
Write down the final equation to get the answer, which is finding the difference between 56 and -55:
Two negatives again...they make a positive, so re-write the equation:
56 - (-55) = 56 + 55
Get the answer by solving:
56 + 55 = 111

You have the adjacent and hypotenuse so you will use Cosine
cos=adj/hyp
adj=3
hyp=5
3/5 = cos (or theta)
The volume would be 0.9 x 4.2
This means it is 90% smaller
Don't forget to round the nearest tenth place. That's the first decimal, so you answer should only have 2 digits.
