Answer:
Distance to Gateway Arch from Plane = 122862.14 ft
Step-by-step explanation:
Refer the given figure.
We have
[tex]sin 19 =\frac{BC}{AC}\\\\sin 19 =\frac{40000}{\texttt{Distance to Gateway Arch from Plane}}\\\\\texttt{Distance to Gateway Arch from Plane} =\frac{40000}{sin19}\\\\\texttt{Distance to Gateway Arch from Plane}=122862.14ft[/tex]
Distance to Gateway Arch from Plane = 122862.14 ft
