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 30o

Now, in △ABD

cos30o=ADBD⇒BD=23AD⇒AD=32×8

also, in the same Triangle

tan30o=BDAB⇒AB=38

∴  Height of tree =AB+AD=(316+38)m=324m=83m

Answer:

80%

Step-by-step explanation:

Total number of trees=80

Number of trees broken=16

Therefore trees left in good condition=(80-16)=64

Therefore percentage of trees in good condition

= (64/80)×100%

=(8×10)%

=80%

Thus,80% trees are left in good condition after the storm.
