Question

The angle of elevation of the top of a tree is 60°. If the point of observation is 4m from the foot of the tree. How far is the point from the top of the tree?

Answer 1

8m

Explanation:

x = hypotenuse since they want the point of observation to the top of the tree

cos 60 = 4/x

x = 4 / cos 60

x = 8m
