What is the inverse of the function f(x)=x+ 3? -h(x)= 1/3x+3

-h(x)= 1/3x-3

-h(x)= x-3

-h(x)= x+3

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
