# A bird is sitting

On the basis of condition given in the question the figure can be drawn as:

Let us assume BC be the tree and BD be x and AB be y

Now in right triangle ABC, we have

(i)

Also, in right triangle ADE we have

Now putting the value of y from (i), we get

x = 80 (1.732 – 1)

= 80 × 0.732

= 58.56 m

We know that,

= 29.28 m/sec
