You can't use sin, because you don't know the hypotenuse. Using sin would give you the height, which is 320 meters. You want to find x, which is the distance. For that, you use tangent

You could also use cosine, but only if the hypotenuse was given, which it isn't

Of course, it would be 1194 meters, don't forget the units

You're finding the wrong side. The question asks for the distances directly under the point from the top, which is side x in my drawing.

You would solve for the hypotenuse if you're trying to find bearings
