Answer:
![d=9.2](https://tex.z-dn.net/?f=d%3D9.2)
Step-by-step explanation:
Distance Formula: ![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:
![d=\sqrt{(1-8)^2+(1-(-5))^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%281-8%29%5E2%2B%281-%28-5%29%29%5E2%7D)
![d=\sqrt{(-7)^2+(1+5)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-7%29%5E2%2B%281%2B5%29%5E2%7D)
![d=\sqrt{49+(6)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B49%2B%286%29%5E2%7D)
![d=\sqrt{49+36}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B49%2B36%7D)
![d=\sqrt{85}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B85%7D)
![d=9.21954](https://tex.z-dn.net/?f=d%3D9.21954)

Step-by-step explanation:

Answer: The distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
Step-by-step explanation:
Since we have given that
Distance between Ships A and B = 1425 feet
Angle of depression from ship A to the submarine =59°
Angle of depression from ship B to the submarine = 47°
As shown in the figure below:
Remaining angle will be
![180\textdegree-(47\textdegree+59\textdegree)\\\\=180\textdegree-106\textdegree\\\\=74\textdegree](https://tex.z-dn.net/?f=180%5Ctextdegree-%2847%5Ctextdegree%2B59%5Ctextdegree%29%5C%5C%5C%5C%3D180%5Ctextdegree-106%5Ctextdegree%5C%5C%5C%5C%3D74%5Ctextdegree)
So, we will use "Sine formula ":
![\frac{\sin 74\textdegree}{1425}=\frac{\sin 59\textdegree}{B}\\\\B=\frac{1425\times \sin 59\textdegree}{\sin 74\textdegree}\\\\B=1270.68\ feet](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%2074%5Ctextdegree%7D%7B1425%7D%3D%5Cfrac%7B%5Csin%2059%5Ctextdegree%7D%7BB%7D%5C%5C%5C%5CB%3D%5Cfrac%7B1425%5Ctimes%20%5Csin%2059%5Ctextdegree%7D%7B%5Csin%2074%5Ctextdegree%7D%5C%5C%5C%5CB%3D1270.68%5C%20feet)
Similarly,
![\frac{\sin 74\textdegree}{1425}=\frac{\sin 47\textdegree}{A}\\\\A=\frac{1425\times \sin 47\textdegree}{\sin 74\textdegree}\\\\A=1084.18\ feet](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%2074%5Ctextdegree%7D%7B1425%7D%3D%5Cfrac%7B%5Csin%2047%5Ctextdegree%7D%7BA%7D%5C%5C%5C%5CA%3D%5Cfrac%7B1425%5Ctimes%20%5Csin%2047%5Ctextdegree%7D%7B%5Csin%2074%5Ctextdegree%7D%5C%5C%5C%5CA%3D1084.18%5C%20feet)
Hence, the distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
Since 88 has no decimal, you would but a zero behind it and then subtract. You have to borrow from the 8 (make it a 7) and make zero 10. Then subtract. 10-7=3, 7-3=4, 8-4=4. Your answer will be 44.3
