It is a Kite because right now we are learning about that
Answer:

Step-by-step explanation:
Let's call
the balloon's height above the ground and
the horizontal distance between the balloon and the first milepost.
If the angle of the depression of this milepost is 24 degrees, we can say the following:

<em>
(equation 1)</em>
For the next milepost, the horizontal distance between the balloon and tihs milepost will be
and the angle of depression will be 20 degrees, so we can say the following


then, replacing from <em>equation 1</em>




Resolving, we'll find the value of 

So, the balloon's height above the ground is 1.99miles
4ab / 8c
a=8
b=4
c=12
4 x 8 x 4 / 8 x 12 = 192
Hope this helped!!!
