Answer 1

We know that total width of the river is 100 m.

Also the tree is in middle of the island or we can say middle of river.

So,

Let there is two triangle ABC AND ABD

now in ABC tan 30 = ab / BD

1/root 3 = ab / 50

50 = BD root 3

Therefore, bd= 50/root 3 m

Hence the height of tree is 50/ root 3 m

Hope it will really help
