Answer:
The number of machines to complete job in 2 hours is 6.
Step-by-step explanation:
Using the relation of the rate of each one machine and knowing that adding up both rates.

Rate R =
'x' is the job
Rate S =
'x' is the job
So, using the equation of rates

Rate total is going to be a job in 2 hours so = 
<em>adding up</em>
<em>factoring the x</em>
<em>simplifying</em>
x= 
x= 6

Answer in terms of a trigonometric function :
Answer in figures

Step-by-step explanation:
Consider the sketch attached below to better understand the problem.
Let x be the distance between point B and the base of the water tower.


From equation 2,
substituting the value of x into equation 1, we get


cross multiplying,



The height of the tower is
in terms of the trig function "Tan"
The equation can simply be evaluated to get the answer in figures since the angles are given in the question
