HELLLP ASAP An observer (O) spots a bird flying at a 55° angle from a line drawn horizontal to its nest. If the distance from the observer (O) to the bird (B) is 15,000 feet, how far is the bird (B) from its nest (N)? Round to the nearest whole number.

A- 8,604
B-12,287
C-18,366
D-21,422

Step-by-step explanation:

This is very obviously a right triangle problem. Side BO is the hypotenuse of the triangle, measuring 15000'. Side BN is the side adjacent to the given angle B, 55 degrees. This is the cosine ratio:

We will fill in what we know:

and solving for x:

15000cos(55) = x

Do that on your calculator in degree mode in exactly that order and get that

x = 8603.6 or, rounded as we need:

x = 8604, choice A.

51-50

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
