Answer:
c=19.5324
Step-by-step explanation:
In given triangle ABC, we have been give values of angle B=55 degree, angle C is right angle and b=16.
Now using those values, we need to find the value of side b.
apply formula of sin
![\sin\left(B\right)=\frac{AC}{AB}](https://tex.z-dn.net/?f=%5Csin%5Cleft%28B%5Cright%29%3D%5Cfrac%7BAC%7D%7BAB%7D)
![\sin\left(55\right)=\frac{16}{c}](https://tex.z-dn.net/?f=%5Csin%5Cleft%2855%5Cright%29%3D%5Cfrac%7B16%7D%7Bc%7D)
![0.819152=\frac{16}{c}](https://tex.z-dn.net/?f=0.819152%3D%5Cfrac%7B16%7D%7Bc%7D)
![0.819152c=16](https://tex.z-dn.net/?f=0.819152c%3D16)
![c=\frac{16}{0.819152}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B16%7D%7B0.819152%7D)
![c=19.5323944762](https://tex.z-dn.net/?f=c%3D19.5323944762)
Hence final answer rounded to four decimal places is c=19.5324

<h2><em><u>
Answer:</u></em></h2>
Total Surface Area = 375 ![ft^2](https://tex.z-dn.net/?f=ft%5E2)
<h2><em><u>
Step-by-step explanation:</u></em></h2>
You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls
<u>Area of the ceiling:</u>
c = length * width
c = 9*6.5 = 58.5
<u>Area of the 2 rectangle walls:</u>
w = 2(length * width)
w = 2(9 * 8)
w = 2(72)
w = 144
<u>Area of floor:</u>
f = 9 * 7.5
f = 67.5
<u>Area of the two trapezoids:</u>
![t = 2(h * \frac{a + b}{2})](https://tex.z-dn.net/?f=t%20%3D%202%28h%20%2A%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D%29)
a = 6.5
b = 7.5
h = 7.5
![t = 2(h * \frac{a + b}{2})](https://tex.z-dn.net/?f=t%20%3D%202%28h%20%2A%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D%29)
![t = 2(7.5 * \frac{6.5 + 7.5}{2})](https://tex.z-dn.net/?f=t%20%3D%202%287.5%20%2A%20%5Cfrac%7B6.5%20%2B%207.5%7D%7B2%7D%29)
![t = 2(7.5 * \frac{14}{2})](https://tex.z-dn.net/?f=t%20%3D%202%287.5%20%2A%20%5Cfrac%7B14%7D%7B2%7D%29)
![t = 2(7.5 * 7)](https://tex.z-dn.net/?f=t%20%3D%202%287.5%20%2A%207%29)
![t = 2(52.5)](https://tex.z-dn.net/?f=t%20%3D%202%2852.5%29)
![t = 105](https://tex.z-dn.net/?f=t%20%3D%20105)
Total Surface Area = c + w + f + t
Total Surface Area = 58.5 + 144 + 67.5 + 105
Total Surface Area = 375 ![ft^2](https://tex.z-dn.net/?f=ft%5E2)
