A flay pole is placed at the top of a tower.the angle of elevation of the bottom and top of the flay pole from a point on the ground 10M away and 40 degrees and 50degrees respectively.find the length of the flay pole.

Answer 1

let height of tower be h m
let height of "flay" pole be f m

two right-angled triangles:

tan40 = h/10
h = 10tan40

tan 50 = (h+f)/10
h+ f = 10tan50

continue

Answer 2
