Question

a tree is broken by the wind the top Duster ground making an angle of 30 degree and at a distance of 30 M from the foot of the day what was the height of the tree

Answer 1

Answer:

51.96 m

Step-by-step explanation:

Let AB be the tree. Suppose the tree is broken at C.

OC = CB = y m

OA = 30 m (given)

In  OAC,

tan 30o =

x/30

or x = 10m

Also, cos 30o =  

30/y

y = 20

root 3

Height of the tree = (x + y) m = 30

root 3

m = 51.96 m
