The <span>height of the tower. is 27 m
Now, we write h/x = tan 45
i.e h/x = 1
i.e h = x ...........................1.
Now, h/(x+20) = tan 30
i.e </span> (x+20)/h = 1/tan 30
or (x+20) = 1.73h
or from equation 1 ,
h+ 20 = 1.73 h
20 = 1.73h - h
h = 20/0.73
or h = 27.39 = 27 m

The equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
<h3>How to determine the equivalent function?</h3>
The expression is given as:
14r^4y^6/7r^8y^2
Start by dividing 14 by 7
2r^4y^6/r^8y^2
Next divide y^6 by y^2
2r^4y^4/r^8
Lastly divide r^4 by r^8
2y^4/r^4
Hence, the equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
