An observer (O) spots a bird flying at a 42° angle from a line drawn horizontal to its nest. If the distance from the observer (O) to the bird (B) is 17,000 ft., how far is the bird (B) from its nest (N)?

Cos(42)=x/17000
X=17000cos(42)
X=170000.743
X==12,631

11375.22 ft. far is the bird (B) from its nest (N).

Height and distance

It is the application of trigonometry

Geven

Angle = 42 degree

Distance between observer and bird = 17,000 ft.

How to calculate the distance?

\(\begin{aligned} \rm sin\theta &= \dfrac{distance\ between\ bird\ to\ nest}{distance\ from\ the\ observer\ to\ the\ bird\ } \\sin42 &= \dfrac{BN}{17,000} \\BN &= 11375.22 \end{aligned}\)

Thus, 11375.22 ft. far is the bird (B) from its nest (N).
