The bearings of two lines AB and AC are N 90º W and S 90ºW respectively. The included angle BAC will be:
180º
90º
0º
None of the above
0º
AB & AC are parallel to each other and in same direction.
So, angle between them is 0°.
Alternative method:
Change bearing of line AB, from QB to WCB
AB = 360° – 90° = 270°
And bearing of line AC = 180° + 90° = 270°
The included equal BAC will be
270° – 270° = 0°
