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.
Answer:
correct answer is b
Step-by-step explanation:
7) A. A variable is an unknown value, and x is unknown. Constants are known values so they cannot have X in it.
8)A again for the same reason as number 7
Answer:
38.5 kg of grass
Step-by-step explanation:
We can solve this problem by using a proportion. (Kg of grass over horses)
Let x = the amount of grass 11 horses will eat in the same period of time.
112/32 = x/11 Cross multiply
1232 = 32x Divide both sides by 32
x = 38.5
I hope this helped and please mark me as brainliest!
If 42 is the area and the formula is bh1/2 then 42 times 2 = 6x to sold x we do 84 divided by 6 and x= 14 the height of the triangle.is 14
