Deadly_king:
Yeah......i got it as well.

Its a simple triangle with one side 195m and another side 170m with the angle between these two sides being 10*. The question just ask you to find the other side.

Hence you need to use cosine rule. Thats all.

Actually the question is quite misleading but not difficult :)
