S50E vs S40W
Doesn't that form a 90° angle?
So you have a right-angled triangle with legs of 7 and 24, and you are looking for the hypotenuse.
Pythagoras anyone ?
From a point on the edge of the sea, one ship is 24km away on a bearing S50E and another ship is 7km away on a bearing S40W. How far apart are the ships?
