an observer (o) spots a bird flying at a 35° angle from a line drawn horizontal to its nest. if the distance from the observer (o) to the bird (b) is 21,000 ft., how far is the bird (b) from its nest (n)? round to the nearest whole number.
a) 12,045 feet
b) 14,704 feet
c) 16,980 feet
d) 17,202 feet

The correct option is D) 17,202 feet.

Step-by-step explanation:

Consider the provided information.

The required diagram is shown below:

It is given that the distance from the observer (O) to the bird (B) is 21,000 ft.

Let x is the distance between Nest and Bird.

As we know

The value of

Hence, the distance between bird (B) from its nest (N) is 17,202 feet.

Thus, the correct option is D) 17,202 feet.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
