The angle of elevation of the top of a tree 39m
away from a point on the ground is 30o. Find the height of the tree
  • A.
    39√3m
  • B.
    13√3m
  • C.
    13/(sqrt{3})m
  • D.
    13/3(sqrt{3})m
  • E.
    (sqrt{3})/13m
Correct Answer: Option B
Explanation

x/25 = tan 30o
x = 39 x 1/√3 = 13√3m
