**Henry**, Wednesday, May 22, 2013 at 11:40am1. d = 20m[45o] + 50m[110o]

X = 20*cos45 + 50*cos110 = -2.96 m.

Y = 20*sin45 + 50*sin110 = 61.1 m.

tanAr = Y/X = 61.1/-2.96 = -20.64189

Ar = -87.23o = Reference angle.

A = -87.23 + 180 = 92.8o

d = Y/sinA = 61.1/sin92.8 = 61.2 m.= AC.

2. Bearing = 92.8-90 = 2.8o West of North.
