An observer (o) spots a plane flying at a 55° angle to his horizontal line of sight. if the plane is flying at an altitude of 21,000 ft., what is the distance (x) from the plane (p) to the observer (o)?

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.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
