Answer 2

Given that:

• A man is standing at a level of 10 m above the water.

• Angle of elevation of elevation of the top of hill is 60° .

• Angle of depression of the foot of hill is 30° .

To Find:

• Distance of hill from the ship and height of the hill.

Formula used:

• tan30° = 1/√3

• tan60° = √3

Solution:

Let the distance of the ship from the hill be x.

So, tan30° = 10/x

x = 10 √3 m....(1)

Now, Let the original height of the ship be h.

So, Again Using the above formula, we have

tan60° = (h-10)/x

√3 = (h-10)/10√3

30 = h - 10

h = 40 m.

So, height of the hill is 40 m and distance of the ship from base is 10√3 m.
