The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
 Tan(α)=Opposite leg/Adjacent leg
 α=30°
 Opposite leg=x
 Adjacent leg=200 feet
 When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:
 Tan(α)=Opposite leg/Adjacent leg
 Tan(30°)=x/200
 
 You must clear "x":
 x=200xTan(30°)
 Therefore, the value of "x" is:
 x=115 feet
<span>
 How high above the ground the is the helicopter?
 The answer is: 115 feet</span>

Answer:
Both processes are correct.
Step-by-step explanation:
Let the mile taken by Chase be 10miles .
He doubles it so it will be 20 and
20% of 20 will be 4 
20-4 = 16km
Now Alex operations
(10/5 )*8 = 2*8= 16 km
In both cases the answer will be the same 
1 mile = 1.60034 km
Now 10 miles = 16.00 34 km 
which is the same as above. 
Both the processes are correct.
