Answer:
Option 3. 71 ft. is the distance between B and top of the hill.
Step-by-step explanation:
Let the height of the hill is h ft and the distance of A from the hill be x ft and distance from B to hill is y.
It is given distance between A and B is 45 ft. ∠BAO = 65° and ∠ABO = 80°.
We have to find the distance of B from the top of the hill.
Now from ΔACO 

From ΔBCO 
h = 5.67x
Now h = 5.67x = 2.14(45-x)
5.67x = 96.3 - 2.14x
2.14x + 5.67x = 96.3
7.81x = 96.3
x = 96.3/7.81 = 12.33 ft
Therefore 


Therefore 71 ft is the distance between B and the top of the hill.

I don’t know what model/formula you are supposed to be using.
But what I did first was calculated what 30% of 2700$ is.
2700 x .3 = 810
So it depreciates $810 per year.
$810 x. 3 years = 2430
2700 - 2430 = 260
In three years, the laptop will be worth $260
Because it is in the middle of those given points
