Ships A and B are 1,425 feet apart and detect a submarine below them. The angle of depression from ship A to the submarine is 59

andreyandreev [35.5K]

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

$180\textdegree-(47\textdegree+59\textdegree)\\\\=180\textdegree-106\textdegree\\\\=74\textdegree$

So, we will use "Sine formula ":

$\frac{\sin 74\textdegree}{1425}=\frac{\sin 59\textdegree}{B}\\\\B=\frac{1425\times \sin 59\textdegree}{\sin 74\textdegree}\\\\B=1270.68\ feet$

Similarly,

$\frac{\sin 74\textdegree}{1425}=\frac{\sin 47\textdegree}{A}\\\\A=\frac{1425\times \sin 47\textdegree}{\sin 74\textdegree}\\\\A=1084.18\ feet$

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.

1.Morgan drives 24 miles due north, then drives 7 miles due east from home to work. What is the distance between Morgan’s home a

Naily [24]

Answer:

1) 25 miles

2) 20 m

Step-by-step explanation:

Number 1 is going to be

$a^{2} + b^{2} = c^{2}$ because it's a right triangle

$24^{2}$ + $7^{2}$ = $c^{2}$

625 = $c^{2}$

c = 25 mile

Number 2 uses the same process, but changing to using C instead of A

a^2 = c^2 - b^2

a^2 = 625 - 225

a = \sqrt(400)

a = 20m
