**Henry**, Sunday, November 18, 2012 at 8:04pmV = 16Knots @ 135o+15Knots @ 195o.

X = 16*cos135 + 15*cos195 = -25.80 Knots

Y = 16*sin135 + 15*sin195 = 7.43 Knots.

tanA = Y/X = 7.43/-25.80 = -0.28798

Ar = -16.07o = Reference angle.

A = -16.07 + 180 = 164o = Direction.

V = X/cosA = -25.80/cos164 = 27 Knots.
