Answer 1

Answer:

I will gladly assist you with your problem! (see explanation)

Step-by-step explanation:

Suppose that the tower's height is t and that the necessary distance is x.

To determine the value of t, use comparable triangle ratios:

$t / 10 = (9 + 3) / 3t / 10 = 4t = 40 feet$

Use Pythagorean Theorem  to find the value of x:  

$x^{2} =40^{2} +(9+3)^{2} \\x^{2} =1600+144\\x^2=1744\\x=\sqrt{1744} \\x= 42 feet$(answer is rounded)
