The height of the observation deck is approximately 47.266 feet.
Step-by-step explanation:
We include a geometrical representation of the statement in the image attached below. Let be O the location of the observation deck, and A and B the locations of the two deers, which are 108 feet apart of each other. By knowing that sum of internal angles within triangle equals 180º. The angles O, B and A are now determined:
By the law of Sine we determine the length of the segment OB:
If we know that
,
and
, then the length of the segment OB is:
Lastly, we determine the height of the observation deck by the following trigonometric identity:
If we know that
and
, then the height of the observation deck is:
The height of the observation deck is approximately 47.266 feet.
