Answer:
[tex]x\approx 1498.4\text{ m}[/tex]
Step-by-step explanation:
We can solve for x using the trigonometric ratio sine:
[tex]\rm\sin(\theta)=\dfrac{opposite}{hypotenuse}[/tex]
↓ plugging in the given values
[tex]\sin(22\°) = \dfrac{x}{4000}[/tex]
↓ multiplying both sides by 4000
[tex]x = 4000\sin(22\°)[/tex]
↓ evaluating using a calculator
[tex]\boxed{x\approx 1498.4\text{ m}}[/tex]
