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 ft., how far is the bird (B) from its nest (N)? Round to the nearest whole number.
These are the choices:
A) 8,604 Feet
B) 12,287 Feet
C) 18,366 Feet

Best ResponseYou've already chosen the best response.0Okay, then you'd do cos 55 into the calculator which gives you: 0.57357. Then I'd multiple 15,000 into 0.57357?
