The problem is wind that the direction co signs on the direction the angles of the reactor I my studio Manus Enrique. First, the magnitude of this factor is in court. To which of one US or past mine this's he caught your motive for King, then behalf the direction Kasay's resigned Alfa is equal to one over fourteen. Assign. Waiter, it's the culture negative two over fourteen. The same dilemma. If we could connective three over your turf or king. So we half author is about thirty forty. Greece. It's about one to two degrees. Come on is about well for three degrees.
