YES!!! it is 360 - 117 = 243
For bearing (navigation) . Bearing of due North is bearing zero(0) . Then moving around the compass clockwise due East is bearing 090 , die South is bearing 180 and due West is bearing 270 .
However, if starting at bearing zero(0) and moving ANTI-Clockwise , the first bearing is 270 , which is 90 degrees of turn. The 90 degrees in anti =clockwise is the inverse.
NB For ALL bearings you quote three digits. So due East , bearing 90 is quoted as '090'. This is normal navigational practice.

If I understand the use of "reciprocal" correctly, the answer is 249 degrees.
compass bearing 271
the bearing of something is the angle. for example there are 180 degrees on a straight line so the bearing of a straight line is 180 degrees. To work out the bearing of something though you need a protracter
It is: 63 degees
With great difficulty because to get back where you started from you add 180 degrees clockwise and 300+180 = 480 degrees which is impossible but if you meant 30 degrees then the back bearing will be 30+180 = 210 degrees
