**Henry**, Monday, September 13, 2010 at 2:41am15 deg. E of S = 285 deg CCW from 0 deg

X = HOR = 25cos(285) - 55 = -48.5,

Y = VER = 25sin(285) = -24.15,

tanA = Y/X = -24.15/-48.5 = 0.4979,

A = 26.47 deg. = 206.47 deg.(3rd quad.)

d = Y/sinA = -24.15/sin(206.5)=54.18mi

d = 54.18 mi @ 206.47 deg.

a. 54.18 mi N @ 63.5 deg W of South

Location: 3rd QUADRANT.

B. D = 2 * 54.18 = 108.36 MILES
