Please solve it
It's so annoying when someone posts a problem, and then follows up with a comment like "solve it." Well, duh, I think we figured out that was what you wanted.
As usual, draw a diagram, and you can see that you need to use the law of cosines. If the distance is x, then
x^2 = 25^2 + 200^2 - 2*25*200 cos115°
