Answer:
383.4 km
Step-by-step explanation:
The interior angle at the first turning point in the triangular flight path has measure 270° -215° = 55°. The law of cosines can be used to find the length of the final leg:
c² = a² +b² -2ab·cos(C)
c = √(125² +137² -2·125·137·cos(55°)) ≈ √14749.01 ≈ 121.4
The total length of the journey is then ...
round trip = 125 +137 +121.4 = 383.4 . . . km
___
In the attachment, the number at the bottom is the sum of the lengths of the two adjacent sides. The total length is then 125 +258.4 = 383.4 km.

<span>Pearson's correlation coefficient 'r' measures the degree to which two variables are correlated. The value is between -1 and 1. Negative values correspond to negative correlation (as one variable increases, the other variable decreases) whereas positive values correspond to positive correlation. The larger the absolute value of r, the closer a correlation graph resembles a set of points on the same line.
Therefore, if two variables are completely correlated, the correlation value is 1 or -1, depending on whether the correlation is positive or negative.</span>
