ANSWER
405m
EXPLANATION
We know the opposite side of of the right triangle to be 4629m and the given angle is 85°.
Since we want to find the adjacent side which is x units, we use the tangent ratio to obtain,
[tex] \tan(85 \degree) = \frac{opposite}{adjacent} [/tex]
[tex] \tan(85 \degree) = \frac{4629}{x} [/tex]
Solve for x.
[tex]x = \frac{4629}{\tan(85 \degree)} [/tex]
x=404.985
To the nearest meter, x=405m
