**Henry**, Saturday, May 28, 2011 at 11:43amVp=225mi/h@(270-25) + 60mi/h@(270+80).

Vp = 225mi/h@245deg + 60mi/h@350deg.

Vp=(225cos245+60cos350) +

i(225sin245+60sin350).

Vp = (-95.1+59.1) + i(-203.9-10.4),

Vp = -36 - i214.3,

1. tan(Ar) = -214.3 / -36 = 5.95,

Ar = 80.5deg.

A = Ar + 180 = 80.5 + 180 = 260.5deg. =

Direction(bearing).

2. 90 - Ar = 90 - 80.5 = 9.5deg. = smallest angle.

3. 90deg = Largest angle.

4. 90 - 9.5 = 80.5deg.

5. Vp^2 = (-36)^2 + (214.3)^2 = 47,220.49,

Vp = 217.3mi/h.
