Ответ:
25641 feet
Step-by-step explanation:
It is given that An observer (O) spots a plane flying at a 55° angle to his horizontal line of sight and the plane is flying at an altitude of 21,000 feet.
Thus, from the figure, OP=x feet, PA=21,000ft and m∠O=55°
Now, using the trigonometry, we have
Substituting the given values, we get
Therefore, the distance x from the plane P to the observer O is 25641 feet.
