The width of the cooling tower at the base of the structure will be A. 36 meters.
<h3>How to calculate the width?</h3>
From the information given, the towers walls are modeled by x²/324 - (y² - 90)²/1600.
Therefore, the width of the cooling tower at the base of the structure will be:
= 2 × ✓324
= 2 × 18
= 36
In conclusion, the width is 36 meters.

.
Let

.
Profit made through $
paintings is ![50x](https://tex.z-dn.net/?f=50x)
Profit made through $
paintings is ![75y](https://tex.z-dn.net/?f=75y)
So,total profit is given by ![50x+75y](https://tex.z-dn.net/?f=50x%2B75y)
It is given that total profit is $![2975](https://tex.z-dn.net/?f=2975)
So,
..(i)
Given that the total number of prints is ![52](https://tex.z-dn.net/?f=52)
So,
..(ii)
using (i) and (ii),
![50x+75(52-x)=2975\\50x+3900-75x=2975\\25x=925\\x=37](https://tex.z-dn.net/?f=50x%2B75%2852-x%29%3D2975%5C%5C50x%2B3900-75x%3D2975%5C%5C25x%3D925%5C%5Cx%3D37)
![y=52-x=52-37=15](https://tex.z-dn.net/?f=y%3D52-x%3D52-37%3D15)
Right angle i think
90 degree angle is right angle so jus Measure it
