Step-by-step explanation:
What are the conclusions?
I would assume that even though both hot chocolate and coffee increased and decreased at the same time, they are not a correlation since one doesn’t cause the other to increase/decrease
2 congruent sides would be an isosceles triangle
The distance between the boat and the ocean's floor is 19m

How to get the distance from the ship to the ocean's floor?</h3>
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.
