Let the Height of the Tree =AB+AD and given that BD=8 m Now, when it breaks a part of it will remain perpendicular to the ground (AB) and remaining part (AD) will make an angle of 30 o Now, in △ABD cos30 o = AD BD ⇒BD= 2 3 AD ⇒AD= 3 2×8 also, in the same Triangle tan30 o = BD AB ⇒AB= 3 8 ∴ Height of tree =AB+AD=( 3 16 + 3 8 )m= 3 24 m=8 3 m
