Answer:

[tex]x[/tex] ≈ [tex]349[/tex]

Step-by-step explanation:

SInce we don't know the side length, we will replace it with [tex]X[/tex] for now.

To make this problem easier, since the angle of elevation = the angle of depression, we can start from the base, and use Tangent.

[tex]Tangent=(\frac{Opposite}{Adjecent})\\[/tex]

  • Opposite of [tex]19[/tex]° = [tex]120\\[/tex]
  • Adjacent of [tex]19\\[/tex]° = [tex]X\\[/tex]

[tex]tan19[/tex]° [tex]= \frac{120}{x}[/tex]

  • then, divide [tex]120[/tex] by [tex]tan19[/tex]°

[tex]120 - tan19[/tex]°  [tex]= x[/tex]

[tex]x[/tex] ≈ [tex]349[/tex]

Okayyyy...... so it's really late right now, but I just found out there was an answer key online. They show all their work, which is pretty nice, so I uploaded/ attached that to this answer, and yes, I promise it's not a scam. Anyways, I gotta head out soon. Good luck on the rest of your homework though! :)
