From the top of a 200 foot building, a bird is sighted overhead and a man is observed directly below the bird at ground level. The angle of elevation of the bird is 16*, and the angle of depression of the man is 43* find :

a) the distance from the top of the building to the man (line of sight)

b) the distance from the top of the building to the bird/man's location (horizontal distance)

c) the distance from the top of the building to the bird (line of sight)

d) the height of the bird flying

(Must show all work) any help would be appreciated!!
