Circle X is shown in the diagram.
Which equation can be used to solve for m 21?
Om21= {(a−b)
O m21= {(a + b)
m21 = {(0-0)
0 m21= {(c + 0)

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0

Pleas its really urgent and i would really appreciate it! what is the value of x? enter your answer in the box. x =

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).
