It tells you "the angle through which the direction of motion of S is deflected is delta degrees". If you don't understand what that sentence means then unfortunately I can't help further as I don't do mechanics, but I'll tag in some who might be able to assist you.

Is it angle of U to the vertical + the angle of V to the vertical or angle of V to the vertical - U to the vertical?
