In the diagram, < WOX = 60o, < YOE = 50o and < OXY =...

Explanation

The bearing of x from y = 270^o + \(\theta\)

where \(\theta\) + 50^o = y

in \(\bigtriangleup\) OXY

O + X + Y = 180^o

Where O = 40^o + 30^o = 70^o

70^o + 30^o + y = 180^o

y + 100^o = 180^o

y = 180^o - 100^o = 30^o

\(\theta\) + 50^o = 80^o

80^o - 50^o = 30^o

The bearing of x from y = 270^o + 30^o = 300^o
