Answer:
1064 ft.
Step-by-step explanation:
Start by sketching out a figure to represent the situation, it should look something like this:
(See picture)
(Figure definitely not drawn to scale)
The angle marked in red measures 4.3°, then we can use the law of sines to solve for the height of the Eiffel Tower (represented as the variable x):
[tex]\frac{sin(4.3)}{80}= \frac{sin85.7}{x}\\x=\frac{80sin85.7}{sin4.3}\\x=1063.96592818...[/tex]
Rounding gives 1064 ft.
