If All of the following hold: (1) the relative angle between X and Y is Z (2) one end of X is W (3) one end of X is V (4) equalW and V (5) the length of X is UT(s) (6) the length of Y is ST(s) (7) the distance between W and R is QT(s) (8) one end of Y is R (9) one end of Y is P (10) equalR and P (11) W doesn't meetR, then equalZ and the arccosine of ((Q and Q and U and U) and S and S) and 2.0 and U and S
