Question

An observer (O) spots a plane (P) taking off from a local airport and flying at a 23° angle horizontal to her line of sight and located directly above a tower (T). The observer also notices a bird (B) circling directly above her. If the distance from the plane (P) to the tower (T) is 5,000 ft., how far is the bird (B) from the plane (P)?

Answer 1

5429 feet 9063 feet 11,779 feet 12,788 feet

Answer 2

OT and BP are congruent sides, therefore, you can solve for OT using trig functions. :)

Answer 3

but ive never done trig b4..so i dont understand it..thats what i told a girl earlier

Answer 7

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)?

Answer 8

11,375 feet 12,633 feet 14,862 feet 15,307 feet

Answer 9

cos(42º) = x ⁄ 17000

x = 17000 • cos(42º)

x = 12633 feet
