Answer»
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
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
