A bearing is an angle, measured clockwise from the
north direction. Below, the bearing of B from A is 025 degrees (note 3 figures
are always given). The bearing of A from B is 205 degrees.
A, B and C are three ships.
The bearing of A from B is 045º. The bearing of C from A is 135º. If AB= 8km and
AC= 6km, what is the bearing of B from C?
tanC = 8/6, so C = 53.13º
= 180º - 135º = 45º (interior angles)
x = 360º -
53.13º - 45º (angles round a point)
(to the nearest whole number)
