Step-by-step explanation:
Given

--- angle of elevation
Required
Determine the height above the ground
The question is illustrated using the attached image.
To calculate the required height, we make use of:

Where AB represents the height and BC, the distance.
So:

Make AB the subject



--- approximated
The range is 8 and if you needed help finding the median it is 2 I think
