Q12 of 28 Page 93

A tree breaks due to storm and the broken upper part of the tree makes an angle of 60° with the horizontal plane. The top of the tree meets the horizontal plane at a distance of 10 m from the root of the tree. Find the height of the tree before breaking. (√3 = 1.732)


Let AB is the Height of the Tree before broken the upper part, DE is the Height of the tree after broken.


Given, ∠DCE = 60o, DC = 10m




ED = 10 × 1.732


ED = 17.32





EC = 2


Total Height of the tree = EC + ED = 17.32 + 20


= 37.32
