Question 550737
A road runs southeast-northwest. A motor home heading northwest on the road makes a left turn onto a side street at an angle of 75.2°. 
Through what angle would a motor home heading southeast on the same road need to turn in order to enter that same side street?
-------
If the 1st vehicle makes a turn of 75.2 degs,
180 - 75.2 = 104.8 degs (to its right)
----------------
I've never seen a compass or GPS that does fractions of degrees.
