Answer:

19.18 km

Step-by-step explanation:

The angle between the directions is 127 - 46 = 81

Use the law of cosines.

Let d = the distance between the ships

d^2 =10^2 +18^2 - 2*10*18 cos 81

= 100 + 324 - 360cos 81

= 424 - 360(.156434...)

= 367.6835

d = 19.18 km

Answer:

Solution,

X=4

Now,

 $5x - 3y = 32 \\ or \: 5 \times x - 3y = 32 \\ or \: 5 \times 4 - 3y = 32 \\ or \: 20 - 3y = 32 \\ or \: - 3y = 32 - 20 \\ or \: - 3y = 12 \\ or \: y = - \frac{12}{ 3} \\ y = - 4$ 

Hope this helps...
