Answer:
[45tan(82°)+123] meters
A is correct
Step-by-step explanation:
You are standing 45 meters from the base of the Empire State Building.
You estimate that the angle of elevation to the top of the 86th floor(the observatory) is 82°.
If the total height of the building is another 123 meters above the 86th floor.
OB = 45 m , ∠O= 82°
In Δ OBA, ∠B = 90°
Top of the building, T at 123 m from A
Total height of building = BA + AT
Hence, The height of building from ground is [45tan82°+123] meters
The graph would look something like this
