Answer:

[tex]184.38\ ft[/tex]

Step-by-step explanation:

we know that

In a right triangle the tangent function of an angle [tex]\theta[/tex] is equal to divide the opposite side to the angle [tex]\theta[/tex] by the adjacent side to the angle [tex]\theta[/tex]

In this problem we have

[tex]\theta=2\°[/tex]

[tex]adjacent\ side=5,280\ ft[/tex]

Let

h-----> the opposite side to the angle [tex]\theta[/tex] (represent the height)

so

[tex]tan(2\°)=h/5,280[/tex]

[tex]h=5,280*tan(2\°)=184.38\ ft[/tex]

see the attached figure to better understand the problem
