The balloon’s vertical distance above the ground is 570.3 feet
<h3>Angle of elevation and depression</h3>
Given the following parameters
The angle of depression = 36 degrees
Base distance =  785 feet
<h3>Required</h3>
 vertical distance above the ground (H)
Using the SOH CAH TOA identity
 tan 36 = H/785
H = 785tan36
H = 570.3 feet
Hence  the balloon’s vertical distance above the ground is 570.3 feet

Here we are given the three sides of the triangle.
So we have Heron's formula to find its area.
Heron's formula is given by :

where A, B and C are sides of triangle and S is semi perimeter which is given by,

plugging values of A, B and C to find S 

S=13.5
Now plugging values of A, B , C and S in Heron's formula

A=26.14 mm²
Answer: Area of triangle is 26.14 mm².
