A

30 m

B

`30 sqrt3` m

C

`(30)/(sqrt3)` m

D

15 m

A peacock is sitting on the tree and observes its prey on the ground. It makes an angle of depression of 22^(@) to catch the prey. The speed of the peacock was observed to be 10 km/hr and it catches its prey in 1 min 12 seconds. At what height was the peacock on the tree? (cos 22^(@)=0.927, sin 22^(@)=0.374, tan 22^(@)=0.404)

Solve any two of the following subquestions : A peacock is sitting on the tree and observes its prey on the ground . It makes an angle of depression of 22^(@) to catch the prey . The speed of the peacock was observed to be 10 km/hr and it catches its prey in 1 min 12 seconds . At what height was the peacock on the tree ? (cos 22^(@) = 0.927 , sin 22^(@) = 0.374 , tan 22^(@) = 0.404)

A tree breaks due to storm and the broken part bends, so that the top of the tree touches the ground making an angle of 30^@ with the ground. The distance between the foot of the tree to the point where the top touches the ground is 18 m. find the height of the tree ( in metres)
