Question:

Solution:

The situation of the given problem can be drawn in the following right triangle:

This problem can be solved by applying the trigonometric identities as this:

[tex]\tan(2^{\circ})=\frac{y}{10}[/tex]

solving for y, this is equivalent to:

[tex]y\text{ = 10 tan\lparen2}^{\circ}\text{\rparen=0.349 miles}[/tex]

now, 0.349 miles is equivalent to 1842.72 feet. Now, this number rounded to the nearest whole foot is equivalent to 1843.

Then, the correct answer is:

1843 feet.
