Answer:
Step-by-step explanation:
<em>Refer to picture.</em>
Let the distance to men are x and y and the distance between them is d.
The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.
<u>Find the distance from the tower to men:</u>
- x = 20 tan 63° = 39.25 m
- y = 20 tan 60° = 34.64 m
<u>The distance between men is:</u>
- d =

<em>Note, all numbers are rounded</em>
We know that the variation is proportianal, that is we can relate the quantities as:

where y is the mass of the body and x is the mass of water. From the values given we have that:

hence the constant of proportionality is 3/2. Now, if the mass of the water is 75, then the mass of the body is:

Therefore, the mass of the body is 112.5 kilograms
