[tex]\underline{\mathbb{SOLUTION:}}[/tex]

» Creating right triangle, the referred angle is opposite to the height and adjacent is the base. Find x using the tangent ratio.

  • [tex] \rm \tan \theta = \frac{opposite}{adjacent} \\ [/tex]

  • [tex]\tan 39 \degree = \frac{900 \: m}{x} \\ [/tex]

» Exchange x and tan 39°.

  • [tex]x = \frac{900 \: m}{\tan 39 \degree} \\ [/tex]

» Get the approximate value of tan 39°.

  • [tex]x \approx \frac{900 \: m}{0.80978} \\ [/tex]

  • [tex]x \approx 1\text,111.41 \: m[/tex]

[tex] \therefore [/tex] The value of x is approximate 1,111.41 meters.
