Answer:
The ships are 66 meters apart.
Step-by-step explanation:
For the sake of convenience, let us label ships A and B
As shown in the figure, the distances to the ships from right triangles. 
The distance to the ship A is  and it is given by
 and it is given by



And the distance to the ship B is  and is given by
 and is given by



Therefore, the distance  between the ships A and B is
 between the ships A and B is 

In other words, the ships are 66 meters apart.
 
        
                    
             
        
        
        
YES! quite easily.
I hope you can see the two pairs of corresponding angles between the parallel lines. they'll be equal
and then there's a pair of vertically opposite angle at centre.
that means all pairs of corresponding angles are equal, thus, triangles are similar by AAA

Answer:
C)   
Step-by-step explanation:
Line of best fit (trendline) : a line through a scatter plot of data points that best expresses the relationship between those points.
All the given options for the line of best fit are linear equations.
Therefore, we can add the line of best fit to the graph (see attached), remembering to have roughly the same number of points above and below the line.
Linear equation:  
(where  is the slope and
 is the slope and  is the y-intercept)
 is the y-intercept)
From inspection of the line of best fit, we can see that the y-intercept (where x = 0) is approximately 8.  So this suggests that options C or D are the solution.
We can also see that the slope (gradient) of the line of best fit is approximately -0.5 (as the rate of change (y/x) is -1 unit of y for every +2 units of x).
Therefore, C is the solution, and the closet approximation to the line of best fit is 
 
        
             
        
        
        
Answer:
x=17°
Step-by-step explanation:
163+x=180 (L.P)
x=180-163
x=17°
