 A pole stands vertically inside a triangular park Δ ABC. If the angle of elevation of the top of the pole from each corner of the park is same, then in Δ ABC the foot of the pole is at the :
(A) centroid                                 (B) circumcentre
(C) incentre                                 (D) orthocenter.

(D) orthocentre

OD is the vertical pole.

Hence <DOA = <DOB = 90

 It is given that <OAD = <OBD

OD is common to both triangle AOD and BOD

Hence triangles AOD and BOD are congruent.

Therefore OA = OB.

Similarly, OA = OC.

Therefore o is equidistant from A,B and C, and hence is at the orthocentre.

since the angle of elevation of pole is same, which means for a particular height of pole, the distance of pole feet from and any point A,B,C is same

This means that the feet of pole shld be at centroid of triangle ABC

let square root of (-3+4i) = x + iy squaring both sides, -3 + 4i = x^2 – y^2 +2xyi comparing both sides we get, x^2 – y^2 = – 3................(1) and 2xy = 4 xy = 2...................(2)...

Put z = x+iy => |x + iy + 1/(x + iy)| => |[(x+iy)^2 + 1]/(x+iy)| =>|x^2 – y^2 + 2xyi + 1|/|x+iy| => root[(x^2 – y^2 +1)^2 + 1]/root(x^2 + y^2) Now solve it and compare it.
