Answer:
216°
Step-by-step explanation:
The difference between the bearing from B to A and the bearing from A to B is 180°. Here, the difference between the two bearings is ...
6b -b = 180°
b = 180°/5 = 36°
6b = 6·36° = 216°
The bearing of Alton from Barking is 216°.
Answer: OPTION A
Step-by-step explanation:
It is important to remember the "Angle Addition Postulate" in order to solve this exercise.
You have this larger angle:

According to the "Angle Addition Postulate", if the point "C" is in the interior of
, then the measure of this angle can be obtained by adding the angle
and the angle
.
You can observe in the figure that:
Then you get that:

Therefore, the correct answer is Option A.
