4. (07.04 MC) An observer (0) 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)? Round to the nearest whole number.

11779 ft

Step-by-step explanation:

We are given that

Distance between tower and plane,d=5000 ft

We have to find the distance between the plane and bird.

Let x  be the distance between bird and plane

We know that

Using the formula

Hence, the distance between the plane and bird=11779 ft

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
