The sides of a right triangle are related by trig functions of the acute angles. The relationships are described by the mnemonic SOH CAH TOA. The meaning of this is
.. Sin = Opposite/Hypotenuse
.. Cos = Adjacent/Hypotenuse
.. Tan = Opposite/Adjacent
Here, you are given the adjacent side and the hypotenuse for the angle. This means you can use the relation
.. Cos = Adjacent/Hypotenuse
Putting in the given information lets you find x.
.. cos(22°) = x/11
.. 11*cos(22°) = x ≈ 10.199
Answer:hi
Step-by-step explanation:
X= 51 is the answer you need to remember that since they share a straight line you add the together to get 180 which is half a circle
Answer:
The answer is 1825.35
Step-by-step explanation:
Since the first week isn’t included, we only count 4 weeks.
So first, 2000 x 0.03 = 60
(By the way 0.03 is 3%)
2000 - 60 = 1940
Subtracting 2000 by 60 represents the amount of money the aquarium went down in that week.
Then, week 3:
1940 x 0.03 = 58.2
1940 - 58.2 = 1881.8
Now, the last week, week four:
1881.8 x 0.03 = 56.45
1881.8 - 56.45 = 1825.35.
Therefore, 1825.35 after 5 weeks.
