Answer:

x = 3195 ft

Step-by-step explanation:

Trigonometric Ratios are the ratios between sides and angles for a right triangle:

[tex]\boxed{sin=\frac{opposite}{hypotenuse} }[/tex]

[tex]\boxed{cos=\frac{adjacent}{hypotenuse} }[/tex]

[tex]\boxed{tan=\frac{opposite}{adjacent} }[/tex]

Given:

  • angle = 28°
  • opposite = 1500 ft

Question: hypotenuse, therefore we use sin to find the answer:

[tex]\displaystyle sin=\frac{opposite}{hypotenuse}[/tex]

[tex]\displaystyle sin(28^o)=\frac{1500}{x}[/tex]

[tex]\displaystyle x=\frac{1500}{sin(28^o)}[/tex]

  [tex]\displaystyle=\frac{1500}{0.4695}[/tex]

  [tex]=3195\ ft[/tex]
