two men on either side of a cliff 80m high observe the angle of elevation of the top of the cliff to be 30 degree and 60 degree respectivel. find the distance between the two men?

  • 1

320root 3/3

  • -1

let AB BE THE HEIGHT OF THE CLIFF AND CD BE HE DISTANCE AMONG THE TWO MEN

IN TRIANGLE ABC

TAN 30 = AB/BC

1/ROOT 3 = 80/BC

BC = 80 ROOT 3 ......1

IN TRIANGLE ABD

TAN 60 = AB/BD

ROOT 3 = 80/ BD

BD = 80/ROOT 3.......2

THE DISTANCE BETWEEN IS CD

CD = BC +BD

CD = 80ROOT 3 + 80 / ROOT 3

THERFORE CD = 80(ROOT 3 + 1/ ROOT 3)

THUMBS UP...........PLSS
