Question

8. A tree 12 m high is broken by the wind in such a way that it
touches the ground and makes an angle of 60° with the ground
what height from the bottom the tree is broken by the wind ?​

Answer 1

Answer:

h=5.56m

Step-by-step explanation:

Angle made by the unbroken tree with ground = 60∘

Let the height of unbroken part = h

Then height of broken part = 12−h

The broken part, unbroken part and the ground make a right angled triangle.

hence, sin60= h/12

12√3-h√3=2h

h=12√3 / 2+√3

h=5.56 m.
