Answer 2

Hey mate,

Check out the figure in the attachment ⤴

Let the length of AO be H m.

By figure,

CD = OB = 60m

A'B = AB = (60 + H) m

In triangle AOD,

Tan(30°) = AO/OD

= H/OD

H = OD/root(3)

OD = root(3)*H

Now in triangle A'OD,

Tan(60°) = OA'/OD

= OB + BA'/OD

Plug in the values to get,

H = 60m

Height of the cloud from surface of water,

= 60 + 60

= 120m

Hope this helps you out!
